you get banned for breaking rules. and using another account to post outside of the thread talking about your ban while one of your account is still banned is called ban evasion. which is not allowed. so don't post outside of this thread if you don't want to get banned again.
This is most likely the reason reading first post. I'm guessing first account got banned it might have been temp or perma, we dont know. But if OP kept posting on second account it turns into ban evasion like you said and is permanent.
You need to stop making accounts give it a few months (depends on what you did). Come back and ask to be unbanned. And it all depends on what it was for and if mods are nice and unban you. As of right now I have a feeling your perma banned and any account you create will be banned. But give it a few months and only post in meta about it then.
