Blocking Someone on Roblox Is Straightforward, but There Are Gaps in the System

Most people find blocking without much trouble. You open the player's profile, click the three-dot menu, and select Block. That's it. But the feature has quirks that aren't obvious until you've dealt with someone who keeps finding new accounts to harass you. I blocked a kid who made three alternate accounts over two weeks just to continue spamming my chat. The first block worked fine, obviously. The second time, I realized the platform only lets you block by username, not by account ID. When he made a new account, he was completely unblocked automatically. That was the first time I actually paid attention to how limited the system is.

How To Block People On Roblox

Here's the actual process, step by step. First, navigate to the person's profile. You can do this by clicking their username in the chat, visiting their profile page from a game, or searching their exact username in the search bar. Once you're on their profile, look for the three-dot menu button. This is usually located near their username or their avatar display. Click it and you'll see a dropdown list. Select Block from that list. A confirmation prompt will appear asking if you're sure. Confirm it. The block is now active. Once blocked, that player can no longer send you private messages, friend request you, or see your online status. They also won't be able to join private servers you're in. However, they can still see your public profile if you have it set to public, and they can still interact with you in the same public game if neither of you leaves.

There's a workaround for the chat issue. If someone is actively harassing you in a game, blocking them doesn't mute their in-game chat instantly if you're already in the same server. I learned this the hard way. The block takes effect for messaging and friend requests right away, but existing chat sessions can still show their messages until you leave and rejoin the game, or until the session ends. If I needed them silenced immediately, I'd use the report feature at the same time, and then switch servers or leave. Reporting adds a record to their account that moderators can review later. Another thing nobody tells you: Roblox doesn't have a bulk block feature. If someone is making multiple accounts, you have to block each one individually. I've seen people waste twenty minutes going through a list of alt accounts just to block them one by one. There's no shortcut. You also can't see a list of everyone you've blocked without going into your settings manually, which makes it easy to forget you've already blocked someone if they come back with yet another variation of their username. The block list lives under Settings, then Privacy. You can scroll through it there and unblock if you need to. But again, no search function within the block list, which is annoying when you've accumulated a bunch of blocks over time.

One counter-intuitive detail: blocking someone does not prevent them from playing in the same public server as you. It only cuts off direct communication channels like messages and friend requests. If your goal is to completely avoid someone, blocking alone isn't enough. You need to change servers or adjust your game privacy settings so unknown players can't join your private server. The bigger limitation is that blocked users can still send messages to anyone else in your party or friends list. They can also report you back, which means you should consider reporting serious harassment before or alongside blocking. Blocking is a one-way action. Reporting creates a paper trail. Using both together is the only realistic approach if the harassment is ongoing. There's also a mobile-only quirk. On the Roblox app, the block option sometimes appears under a different menu depending on whether you're on the profile page or chatting with the person directly. On desktop, it's consistently in the three-dot menu on the profile. I wasted about five minutes on mobile once because I was looking in the chat bubble menu instead of the profile menu. Just go to their profile page and use the three dots there.

If you're dealing with a persistent harasser who rotates through multiple accounts, the most effective strategy is blocking each new account as it appears, reporting the original account with screenshots, and tightening your privacy settings to restrict who can message you or join your games. The block feature works, but it was never designed to handle repeat offenders by itself. It handles one-off situations fine. Beyond that, you're on your own unless Roblox moderation steps in based on your reports.
