What I found so far:

https://issuehunt.io/ - 10% issuehunt fee - 3.5% stripe fee to deposit also 3.5% to withdraw - search seems good with filters - diverse projects - last tweet in 2019

https://www.bountysource.com/ - 10% withdrawal fee - search seems limited - seems to be almost exclusive to crypto - twitter is active
