The Online ID you are trying to add is already on your block list. Solution: Check that the spelling of the user’s Online ID is correct, taking care to note whether letters are upper or lower case and ensuring that symbols such as underscores and hyphens are inputted correctly. If the Online ID is incorrect, re-enter it correctly. If the Online ID was entered correctly, the user may already be on your block list.
