Pretty much. I suppose the way it’s written isn’t a fuck you, but the fact it’s on the list certainly is. The only way to get more specific is to include your instance. Technically, unless there’s something I’m missing about the block list since I don’t know much, this would match your username but on any instance, not just specifically you on Lemmy.dbzer0.com

Pretty sure that’s regex, so yeah, you’re kinda on the list. If you made a new account with a different number on the end, you’d still trigger the block. If it ended with $ on top of starting with ^, though, then it would need to be an exact match.

Looks like regex. The ^ means it must begin at the beginning of a line of text, and the $ signifies the end of the line. Putting the username between ^ and $ basically means it must be a perfect match with no extras on the end, so if someone had your username plus something extra on the end or with something in front of it, you won’t get a false positive trying to match against your username.
