If there's already a scam accusation to them, don't proceed anymore and forget about them. Wasting your time with those kind of bounty platforms isn't work for your efforts. Go at the bounties and check everything there, it's hard to look at these times but you shouldn't stay to only one platform.
They will not begin to recruit all projects, they need quality, so it’s better to look in other places or platforms!
Exactly, don't get yourself stuck with just one platform.
