Greetings, donation is not needed to play on Sunwell servers its strictly optional, players who donate are not treated any differently from other players and donating does not provide special privileges regarding bans or other issues.
You were banned for afking in multiple Alterac Valley battleground for hours during AV weekend, every time players would report you for afking via ingame anti-afk feature you would run towards an alliance player and attack him just to clear the debuff and then go back to afking, when players asked you why you are afking you responded with "i like wank, it makes me feel good" and then you kept harassing those players through multiple whispers with "are you wanking". You knew that what you were doing is wrong but you didnt stop.
Your ban duration will be reduced to 1 day, however both of your accounts (the one you were banned on and the other one you used to make a threatening ingame ticket while pretending to be someone else) will be given a warning and put on GM watch list because via ingame ticket you demanded that a GM unban you simply because you are a donator and then threatened the GM that you have "200 people behind me on this case and i WILL go public" if you are not unbanned. Warnings on account means that if a GM catches you in similar situation or any other that breaks the rules he will issue you a full duration ban, GM watch list means that a GM will monitor your actions on a daily basis from now on.
