'We' can't.  Only somebody like Theymos could, and that isn't likely to happen.  I would also suggest
that if you have a Hero member account, you can easily earn over $500/month with just one account.  Just
one account!  These farmers who have multiple accounts in multiple campaigns or who are doing airdrops and
whatever else, they have to be living large in Indonesia/Vietnam/Philippines/Wherever.  I understand the
motive very clearly.  The only thing to do right now is to report the garbage posts and the copy/pasters.
Don't expect campaign managers to get banned anytime soon.  I don't care if people have several accounts
in sig campaigns...it's just that the quality of posts from some of these idiots is lower than dirt.  They can't
even write a proper sentence in English, and it's all 'you can get profit by holding or mining investing and
bitcoin is great', that sort of thing.  It makes this forum unbearably dull.
