Yes, now there is a lot of theft, with your identity, I often experience it, indeed the right solution is to send a private message to the manager, then they will know that the account you are using is officially yours,
and the next step you are looking for in a spreadsheet that misuses your account must be removed from participant participation.
The call for bounty participants themselves to be actively seeking out scammers and helping the community manage it with their contributions is a right one, but I wonder,,, is the cause already lost? For every scammer we find, 10 more fill in the gaps. For every tactic and method we discover, they make new ones up. And publicizing the methods for detecting them may actually help scammers avoid detection. So I do not know what the best method is. I prefer just quietly reporting people and seeing them getting banned.
