Ok, what about other bounties? As you know there are a lot of scammers who use inactive and not their bitcointalk usernames and register in 1 action bounties. They just register wallets. To prevent this many bounty managers ask to post "proof" that it is your account and that it is you, who participate in this bounty.
What will you say about it and may be you know how to solve this problem with scammers?
