If you look at the lists of bounty participants, more than half of them are scammers because they offer stolen content. I had such that articles were stolen from me personally, so I had to communicate with managers in order to remove the scammers. Honestly, it's a pity that such a wonderful way of earning money was killed by human greed.
things like that have happened even in the real world. it's just that, people are doing it online more often nowadays. To be honest, now I see that quite a lot of projects become a scam if they make payments without going through escrow. things like scammer prevention have been widely recommended, it's just that there are still more people affected by a scam than those who are not. However, choosing a bounty that has an escrow would be preferable.
