Quick answer (reviewed October 9, 2026): Blocking a Roblox player is an account-level safety action, not the same as reporting rule-breaking behavior or simply leaving an experience. Roblox says a blocked player is not notified, existing friend and follower relationships are removed, and direct messages, invitations and friend requests between the accounts are stopped. You can initiate a block on a profile or from an experience’s player controls. Here is how the supported options differ and what to do if the person is harassing you.
Block a player from their Roblox profile
Sign in to Roblox, open the person’s profile and check that the username matches the person you intend to block. Select the three-dot menu near their profile details and choose Block User. That action is account-specific: blocking the wrong display name is possible if you search only by a nickname. Roblox usernames, rather than display names alone, help distinguish accounts. Revisit the profile to check whether the block option has changed to Unblock.
Block someone while you are in an experience
On desktop, Roblox’s player list or leaderboard may let you select a player’s name and choose Block directly. You can also open the in-experience menu with Esc, use the People tab and confirm the Block action. If the leaderboard is unavailable on a phone, use the person’s profile instead. Blocking is more durable than simply muting audio in a single session because the account-level relationship changes.
What blocking does and does not do
Roblox’s help center confirms that the blocked user does not receive a notification; both users stop being friends or followers, and they cannot contact each other directly through the listed social features. Blocking does not automatically send a moderation report or prove that a user violated a rule. If an inappropriate message, scam attempt or threat occurred, use Roblox’s Report Abuse feature and supply the relevant context.
How a linked parent can block a child’s friend
Parents who have linked their account can open Settings, then Parental Controls, select Friends and Manage, and block a friend from that list. Roblox says this removes the player from the child’s friend list and prevents that child from adding the person again without permission. This is separate from general communication and screen-time controls. Changes to a child account should be made from the linked parent’s settings.
Check the result and handle repeated harassment
After blocking, test the outcome by reviewing the friend list, the block control on the player’s profile and your own communication preferences. Avoid responding to new accounts created to bypass a block. Save relevant evidence privately, report abusive content in context, and avoid sharing login details or recovery codes with anyone offering to ‘fix’ the problem. The official support guide is the best place to check for interface changes.
