This thread... pretty much what's wrong with the game... outside of content.

1.) Make a waiting period for 'new players' (or accounts) to be 'activated' of 24 hours.
2.) Make a time limit on spar (100+ hours for actual battle arena/gs and rated stuff).
3.) Give more experienced/respected players some basic powers that would enable them to judge/stand out in some way when reporting and potentially warp/warn other players when their lag is off the scale or their hacks are showing.
4.) Hire some staff.
5.) Watch the complaints roll in through feedback.
