I doubt the bounty managers care as they only care about exposure. Probably doesn't warrant tagging as it should be up to the bounty managers to remove people like this if they think it's needed. But they just don't care as long as their name gets out there. I can't really blame people doing this either.
Exactly. What you have here is greed preying upon greed. Most of the people claiming these bounties via twitter and facebook are doing so with fake accounts in their dozens so their actual worth to bounty campaigns are slim to none because they're advertising to either no real people or just hundreds of other bounty spammers. The followers of these accounts also consist of the same: other fake throwaway accounts or just more spammers who are following each other just to bolster their own numbers. Bounty campaigns don't really care because any advertising is better than nothing and it's free to them when they've pre-mined a crapcoin so what have they got to lose. All they want is exposure no matter what and of course there are thousands of bounty hunters with their dozens to hundreds of accounts each who are going to capitalise on this and thus the cycle of spam and greed continues.
