NO PVP EXPLOITING
There are four known methods to abuse of it:
MMR Dropping: Losing in arena on purpose to lower own MMR below normal value.
Honor Exploit: Allowing someone to kill you or let you kill his/her toon to get Honor points in locations where it can be done fast and deliberately is not allowed.
Wintrading: Arranged battles in order to profit of its prizes is highly forbidden leading to bans.
Twinks: Using voteshop items with no-level requirements on a low level character to have advantage in PVP against any other players is NOT fair. Doesn't matter how many votepoints or Coins you spent to make it. You are going to have your twink force-leveled and won't be refunded.
Besides it, no afking in bgs,
follow, botting etc. These are bad attitudes that may get your account suspended.
