There were times when altcoins used to pay bounties in Bitcoin or Ethereum, but nowadays the bounty market is so overcrowded with bounty hunters that they are really in no position to dictate the rules. If you will refuse to work for worthless tokens, someone else will. And these ICO scams don't care about quality, they need quantity, because there's still plenty of greedy noobs who are ready to gamble with ICO's as they hope to find a "good project".
Yep. We have to make bounty hunters understand what they are doing wrong. If we manage to do this we will have better bounties and less scam ICOs too.
Just is an extremely difficult job, especially because most of those don't read, they just post.
