That's right. That's actually a good thing to do.
But most of the time, the bounty manager determines which account is the real owner in order of priority, so I'm not worried about that.
I have seen this scenario many times, and like what you said, the bounty manager determines who is the real owner by noticing it in their posting and answering, if it is the same on the old post or not, but many participants who are joining in any campaign, their account who has a higher rank is usually bought only, so theres a possibility that the type of posting will change.
