In order to avoid bounty scams you need to consider 2 things:
1. CHECK THE PROJECT - you need to do research about the bounty, the project team, the whitepaper because some might just copy and paste it, the advisors, roadmap, bounty pool and ofcourse the founder you need to be a good observer, check their background because sometimes by just merely observing and reading you will know right away if the bounty is a scam.
2. CAMPAIGN MANAGER - the one that you should always consider, because if the bounty manager is scammer then the bounties itself is a scam, and it is really obvious if the bounty manager has a negative trust then surely he or she is scammer, one thing to consider also is the rank of the bounty manager the higher the rank the higher the legit factor, you can always do research here there are many list of legit and reliable bounty manager and the list of all bounty manager scammers.
thank you for your kindness!
hope it helps!
more power!
I do completely agree with 1st point of check the project .
but regarding campaign manager rank in forum , then want to tell you something that i saw many good projects use service of full member rank manager , even some do manage bounty themselves so they have only junior member rank account.
What I am trying to say is the higher the rank the greater the responsibility. Say for example the bounty manager is legendary he won't risk his account as a legendary knowing that the campaign is a scam and he himself is a scammer. So if the bounty is being managed by a legendary you can't argue that it is not legit.
