Hack Elimanation Idea

I know there isnt a 100% cure, but i have noticed a trend with ha.cks forming new accounts.Since the banning thats how they are still playing.I think that a person should be limited to 3 accounts max.Yea ips can be changed but most are limited to that.Put a cap on the number of accounts a person can have and this hack infeastation will go down alot.Just a suggestion i think will help alot.
BTW:trying to help all i can ...i sent in 13 hack reports yesterday and got 7 replays today
