Your old username, for example, if your a youtuber, then if you change your username fans can still go to your profile and click "Past Usernames", then they would see that your a youtuber and people dont like bein mobbed by a thousand robloxians.
It's when you post on an old forum thread which hasn't received any replies for quite awhile. In this case, the last reply was in July, and it was Necrobumped/necroposted in October. This thread really does need to be closed, since it's getting off topic now and OP already got his answer.
The original question was: Can you can hide your past usernames?
The answer: Yes, but in special circumstances (such as your personal name that you don't want others to see)
