Unblocking on Roblox is simpler than people make it, but the UI doesn't help.
You go to your profile page, click "Friends" in the top navigation, then switch to the "Blocked" tab. A list of every person you've blocked shows up, along with a button next to each name. Click "Unblock" and it's done. That's it. The person is immediately unblocked and can find you again, send you messages, see your public profile, and interact with you in games. There's no confirmation prompt that asks if you're sure, which I find slightly annoying but manageable. I remember the first time I tried this, I couldn't find the blocked list because Roblox buried it behind the Friends tab without any clear labeling. I scrolled through my friend list for two minutes before I actually noticed the secondary tabs. The platform doesn't highlight this section at all. Once I figured out the navigation, it took about thirty seconds to unblock anyone. One edge case that tripped me up: if someone blocked you, they remain blocked from your side even after they unblock you. I had a situation where a player I'd been playing with for months blocked me during an argument, then apologized and unblocked themselves. I assumed we were clear. We weren't. I still had them on my blocked list. I had to go in and unblock them manually. Just because they unblocked you doesn't mean the reciprocal block disappears automatically. This isn't obvious from the interface and I've seen plenty of new players confused by it on forums.
There are a few things people miss about the blocking system. First, unblocking someone does not send them any notification. They won't know you unblocked them unless they check their friends list or try to message you. Second, if you re-block someone immediately after unblocking them, you don't get a cool-down period or anything like that. It's instantaneous in both directions. Third, blocking affects more than just chat — it prevents direct messaging and friend requests in both directions, but it does not hide them from your game activity or prevent them from seeing your public profile if it's set to public. The mobile app works the same way. Open the app, tap the More button (three dots), go to Settings, then Privacy. From there you can manage your blocked list. The desktop browser path and the mobile path do not always sync perfectly in my experience. I've unblocked people on my phone and then found them still listed as blocked when I opened the website later. Usually it resolves within a few minutes, but I've waited up to ten minutes for the change to propagate. If you're trying to unblock someone urgently, doing it from a desktop browser tends to be more reliable than the app. One limitation worth noting: Roblox doesn't let you mass-unblock. Each person has to be unblocked individually. If you've blocked fifty accounts over the years and decide to clean up your list, you're clicking the Unblock button fifty times. There's no select-all option. This is by design, I assume, to prevent accidental bulk actions, but it's tedious.
Also, blocking and unblocking don't affect existing group memberships. If you're both in the same game group, unblocking someone won't remove them from that group or vice versa. They'll still be able to see your posts in the group feed even if they're blocked from messaging you directly. That distinction matters to some people. If you're dealing with a player who keeps coming back after being blocked — switching accounts, messaging through mutual friends, spamming in-game chat — unblocking them won't solve anything and blocking them again won't help either. Roblox's block system only works between specific accounts. If someone creates a new account, the block doesn't carry over. That's a hard limitation of the system. In those cases, the only real recourse is to report the behavior to Roblox moderation and document the abuse with screenshots and timestamps. I've found that a well-documented report to Trust & Safety has a meaningful response rate, while trying to out-block someone who's determined to reach you is usually pointless.
