The short answer: Start by blocking whole categories, like pornography, dating, gambling, and weapons, on your home WiFi or with a free service like OpenDNS. Then add specific sites by name. Below are the 14 I recommend blocking on kids’ devices. Most aren’t bad on purpose. They’re full of content other people post, with filters that let a lot slip through.
There are billions of websites out there, and plenty of them are wonderful. Some look harmless, but the content people post pushes them into territory you don’t want your kids wandering into. Those are the ones to block.
A router with built-in parental controls makes this easier, and so does a free OpenDNS account, which lets any router block whole categories plus individual sites. I use a Firewalla router AND OpenDNS for double protection.
As you set up parental controls on a device or your home WiFi, add these sites by name. If you can, block them only on kid devices, since adults may have good reasons to use some of them, like Reddit or X.
The Sites I’d Block
1. Toomics.com
Like most sites on this list, Toomics itself isn’t bad, but it doesn’t filter out inappropriate content. It sounds harmless as a “webtoon platform,” but comics on it can be extremely explicit. Put it on your block list.
2. Random video chat sites (Omegle copycats like OmeTV)
Omegle shut down in November 2023, but lookalike sites and apps took its place. They all work the same way: you get matched at random with a stranger for a one-on-one chat. I don’t want my kid chatting online with total strangers, so these get a hard “nope” from me.
3. Reddit.com
Personally, I LOVE Reddit. I even have my own sub. But Reddit is no place for kids. It’s the biggest message board on the internet, and there’s a lot of yucky stuff in there if you go looking for it. Don’t mind me, though. I’m happy in my Veronica Mars sub.
4. Tumblr.com
Tumblr is a photo, video, and blogging platform. It has rules against explicit content, but one simple search can still turn up things you don’t want your kid seeing. It’s easiest to just block it.
5. Chatroulette.com
My first and LAST experience with Chatroulette was enough to keep it blocked forever. When it first came out, I checked it out, like I do with most things I write about. The very first video that popped up was something no one should ever see uninvited. I closed my laptop and never went back.
When a site opens video chats automatically with complete strangers, you’re asking for trouble. Fool me once, Chatroulette.
6. Archive.org
This one is tricky. The site itself isn’t bad, but the access it gives you IS. Archive.org stores copies of websites going back decades, which is fascinating. The problem is that it stores the inappropriate sites too, and filters don’t catch them, because the address is still archive.org, which is usually allowed. Block it so your kids don’t get a back door to the rest of the web.
7. X (x.com and twitter.com)
I use X, so I only block it on my kids’ devices and our guest network. Many parents don’t realize there’s a LOT of pornography on it. Since 2024, X has officially allowed consensual adult content behind a warning, and a warning isn’t going to stop someone who wants to click.
Along these lines, I’d keep a close eye on Pinterest. There’s more inappropriate content there than most parents realize.
8. theChive.com
It claims to be the #1 men’s humor site in the world, and it’s largely humor. But there’s plenty of scantily clad content mixed in. Definitely a nope in my book.
9. Discord.com
Discord is a chat app, not unlike AOL Instant Messenger back in the day. It has “servers,” which are basically chat rooms. It started as a way for gamers to talk, and now kids can easily end up in chats with strangers and come across content that isn’t meant for them. If your kid is already on it, my Complete Parent’s Guide to Discord walks through the settings that matter.
10. Flickr.com
Flickr isn’t inherently bad, but it suffers from the user-content curse, and you can find nudity there. There’s a ton of great art on it, so leave it open on parent devices. If your kid wants to look something up, they can do it on your device with you.
11. AI companion chat sites (like Janitor AI and CrushOn.AI)
These are role-play chatbots, and many are built for adult conversations, with weak age checks. Character.AI is the one most parents have heard of. It ended open-ended chats for users under 18 in November 2025. The sites that never added those limits are the ones to block.
12. “Nudify” AI image sites
These sites turn an ordinary photo into a fake nude, and they’re behind a new kind of bullying in schools. There are too many to block one by one, so block the category on your router or DNS service if it offers one, and talk with your kids about why making or sharing these images is never okay, even as a joke.
13. Kick.com
Kick is a livestreaming site, and its biggest category is slots and casino streams. Those streams carry an 18+ warning, but nothing actually stops a kid from watching someone gamble big for hours. Moderation is also much lighter than on YouTube or Twitch.
14. Prediction markets and sweepstakes casinos (Kalshi, Polymarket, Stake.us)
These are 18+, but betting on sports through these sites has exploded with young adults. People ages 18 to 21 traded $5.4 billion on Kalshi alone this year. If your teen is into sports, block these on their devices before they get curious.
Block Categories, Then Keep Talking
Make sure you’re blocking categories like dating, pornography, gambling, and weapons to cover a broad range of sites. Adding the sites above on top of that raises your protection level.
Even the best filters miss things. Talk with your kids often about pornography, and work out a plan together for what they’ll do if they come across it, so they know exactly what to do and that they can come to you.
Frequently Asked Questions
How do I block a website on my kid’s phone? On an iPhone, use Screen Time’s web content settings. On Android, use Google Family Link’s settings for Chrome. Blocking on your home router or with OpenDNS covers every device on your WiFi, and the video above walks through six different ways to do it.
Do I need to block these on my own devices? Usually not. Several of these sites, like Reddit and X, have legitimate uses for adults. Block them on kid devices and your guest network.
Is blocking websites enough to keep kids safe online? It’s a great first layer, but no filter catches everything. Pair it with regular conversations, so your kids know they can come to you when something slips through.

Roblox is made for kids it has a feature called safechat for ages under 13 and you can’t talk to people on the platform unless in a game and most older players play games made for accounts over 13 so it is useless to bloxk roblox
Chat is not the only reason I do not allow Roblox in my home.
In these following cases, the rest of my comment is invalid:
-your kid(s) are 7 or younger,
-your kid(s) have some mental illness that make them naieve or something,
-your kid(s) have anger issues.
-your kid(s) are intent on cheating/trolling/making others annoyed/distressed / etc..
-you don’t want to listen to my hopefully helpful advice
-Any other weird thing about your kids that would cause negative feelings.
Wait… Isn’t that a bit strict? I respect your decision to keep your kids safe, and depending on how old they are, (for example, if they’re 7 or younger,) I can see why you disallow it; but Roblox isn’t exactly DeviantArt or P***hub. In fact, it’s geared towards children. The same age as kids 7-12 (or older, if you find the one game that’s for all ages). That means swearing, adult content, blood, etc. aren’t present at all in most games. And the exceptions are extremely rare.
And if you do find something bad? There’s a report button you can find on games that’ll get Roblox searching for bad content, and if it finds any, then that game becomes no more. (You can also do it for other users too.) …just make sure they don’t report every jerk on the internet.)
I’d also like to say that I’m not an expert at parenting, and I respect your decision to keep your kids safe (a second time). As for me, I’ve been playing since almost 10 years ago. I’m almost an adult now, and I haven’t encountered anything worthy of “get me out of this game this is terrible.” So… yeah.
And if my ‘being a teenager’ makes my opinion less valid, well, that’s your choice, not mine. I’m just putting out my side of the story. And… side note from being a kid: being too strict will make your kids feel rebellious, unfortunately.
Thank you. This was so helpful.
