Under Review is an availability status for Roblox places. A place is typically put under review by moderators if it is found to be in violation of the Terms of Service. Some examples of a place breaking the Terms of Service include having inappropriate features, not having a chat filter, copyright issues, being a stolen copy of another place or a scam.
Players may receive moderation action for their games being put under review, particularly if it is determined that the game violates Roblox's Terms of Service. Sometimes, Roblox will no longer put the place under review if the creator removes the features that violate the Terms of Service. For example, in June 2017, WWE 2K17 (now WWE 2K18) was no longer put under review after the creator removed a script that allowed players to bypass the chat filter to swear. However, most places that are put under review are unlikely to be reopened.
Some notable places that were put under review include Vehicle Simulator, Town of ROBLOXia, Boys and Girls Hangout, Pokemon Brick Bronze (now permanently deleted), Empire Theater V9, Pilgrim Islands Reborn , Dragon Ball RP: Legends, Work at a Pizza Place, ROBLOX High School, The Neighborhood Of Robloxia and Welcome to ROBLOX Building, a game created by the account ROBLOX.
