If no one does this thing, then cheating will just be rampant especially in the bounty board. It's a valid one if the user found to be abusing the campaign, YOSHIE don't know you're brother from the start heck he should bother to do that. The very first thing when suspected alts are busted they tend to disclose they are brother, sister, mother-in-father-in-law (what?), their cat, which a common culture to busted alt abusers.

You've been caught here https://bitcointalk.org/index.php?topic=5287174.msg55550729#msg55550729 and the one who caught that was YOSHIE too and here was Veleor: https://bitcointalk.org/index.php?topic=2544574.msg45759941#msg45759941 I think 3 attempt was enough.
