Heck no.Just because あなた hate a name doesn't mean あなた should just make a new profile.I'm not a big ファン of my username,but I didn't make a new profile.><
No, i was thinking of making a new one because im a bit bored of my user name too, but i thought it would be too much work, you'd have to let all your ファン know your making a new account so they can add あなた again. Id just leave it if i was you...
there's no point to be honest. no one's bothered about your username, and would あなた really want to start from scratch? thin about it, アップロード all your content over again, gain all your ファン again, it would just be pointless!
