I believe that someone who has not made a note in the accounts of relatives / friends about their connection and begins to tell "stories" only after the abuse is found should blame himself.
Yeah, but the problem with this is that I don't think any new bounty hunters ever bother to read any threads in Meta, Reputation, or Scam Accusations and don't realize that many bounty hunting "families" have gotten red-trusted because they apparently shared a wallet and were linked to each other through blockchain evidence. Thus they have no way of knowing beforehand that this might be a possibility and wouldn't even think to tell anyone in advance of their plans.
Not that I think such a warning would be believed anyway. We've seen so many instances of alt accounts abusing bounties that it sounds like just another far-fetched excuse by members trying to get their tag removed.
I did get a PM from dengineersprof, who gave one reasonable explanation as to why bounty hunters might share a wallet, and I'm not sure why he didn't just post it here. I'll leave it to him to do that if he wants, because I don't want to quote the PM in public since he might not want me to.
