@IrbiS i found out the real reason of ban.
When we get a warning it says we follow three strike warning system then after 3rd warning u get a ban. Do u recall when i was totally new here ,akheilos perhaps had reported that totally normal post of mine that i had showed u . the warning that i recieved had nowhere stated on it how long it stays active etc as in on some forums u get the duration of warning expiration. So ihad clarified to the mod too. But khair infraction wasnt reversed and remained active, then ihad gotten one again ,it was a fight in this thread with an indian harasser/abuser, it got me a ban too(justified or not lets leave it). so this time i had gotten another warning which became the 3rd warning and automatically led to the ban.
Mujhay yahan bilawaja warnings aur ban miltay rehtay hain. :/
