Here you will join a bounty hoping it becomes something worth the time that you put in, heck even good effort in making some content for them - one fine day you see that the team is enforcing KYC for each and every bounty hunter because someone in the pack was caught using hundreds of alt accounts to spam the bounties and defraud them. From the team's perspective it is a valid thing to do. But you might not think it would be safe for you - then what will you do? Nothing legally you can, hence you will just go quiet and let it slide.
This cycle of despair and frustration is there in every bounty hunter who actually works to promote the project, not the spammers.
Hence if you dont wish to see your efforts wasted, go for bitcoin paying campaigns always and buy bitcoin when it goes down.
