I mean, your current account isn't even that old, your old posts don't even seem too bad. If you want to rebrand you could probably ask a staff member to change your name, then you could change your PFP, It's probably better to be able to see your old posts and see how much you've progressed. I've only been on this forum for 2 years and I can look back and see how much better i've gotten at the game, don't you want that for yourself?
