Distance yourself from that Glaceon stuff. It's not cute or funny, it's just straight up creepy and obnoxious. I don't expect you'll be able to change your forum name but ditch the avatar and avoid posting it anywhere but the furry and special interest threads, and
tone it down in those threads, don't give people detail they didn't ask for. I wouldn't stuff on someone for having a weird special interest or obsessive interest but when you incorporate it into your identity it becomes degenerate.
Posting on a message board is a social activity. It's not AS social as talking to be in real life but it's still social. So you still have to hold yourself to some form or another of social formality. RP'ing on a public message board is cringeworthy.
Why don't you try not sticking out. You don't need a good or bad name for yourself. Be a background guy who joins discussions with neutral comments and is not memorable for it.
This is essentially the most excellent advice anyone can give you on this forum, good job putting this into writing lmfao
