The reason as to why trying to become a liked user again isn't working for you is cause you're too chalant about it, constantly worrying about everyone's opinions n shit. See, what you need to do is to work on your reputation but without constantly asking others what you're doing wrong. You gotta be nonchalant and sigma, then eventually, people will forget why they hated you in the first place.
Take it from me. I used to get a lot of flak for my username (and beliefs), but I lowkirkeniunely just didn't give a shit, and now ppl are just kinda chill with me (with the exception here n there, of course).
