Right to Erasure Request
A Right to Erasure request is a message that creators may receive in their inbox from Roblox stating that you must erase all data from the requested experience(s) for a specific user. A Right To Erasure, also known as the right to be forgotten, allows a person to request that they have their personal data erased. This occurs when a user requests "Right to be Forgotten (RTBF)" which requires Roblox to comply with the request. When Roblox has deleted the account and changed the user's name to [Account Deleted (id)], Roblox sends this to any creator of an experience that the user visited prior to making the request.
If any experience(s) contain datastore, that user-id must be removed from the system or risk action against your account.
