That account, firstly, does not exist. If the profile says "aka a FANDOM user", it's just a random username for an account that doesn't exist. Anyone can do that with any username.

The reason the gblock tag is there is, as you said, because any username including "vstf" is automatically blocked - which also prevents any account from being created with that name.
