Back then, I made some sorts of mistakes; I'm stating this and clearly confessing my mistakes.
some sort of mistake, lol. you are only "clearly confessing" because you got caught.
However, the negative trust in my profile is affecting me on the forum; It's forcing me to create an ALT account and use it, which is also not allowed in this forum. Then what should I do?
that's your problem, you should have thought of that before deciding to cheat with multiple accounts.
there was some fault of mine also.
it was ALL your fault, not some.
Can all this be reverted again?
no, so don't waste your time.
and i would not be surprised if you get more red tags.
