Your question for me the answer is
'bad' treatment that there is no tolerance for those who do it, for victims who can prove that they have nothing to do with members of the ill treatment, my response is fine, not for members who do, that's a different story.
I've handled cases like that, novice members who use the identity of other members participate in the Bounty.
Example:Topic: Account of committing a crime.They register, using address, twitter, facebook etc.
After checking, it turns out that the user who is actually the original owner has never participated in the Bounty campaign and they admit it.
So, actions for members who do bad deeds like that should be marked it can damage the reputation of others, that's just a few cases,
But not a little bit it's true they are real Alt, cornered admit, it's uncle, aunt etc.Conclusion: there are own methods to prove such cases, usually knowing their situation is alt genuine or not alt stealing someone else's property, only those who ride the case know the origin of the game, usually it doesn't get picked up right away, it takes a week, then it's lifted and knows the truth.
