for escrow matters, these are often managed by well-known managers like Hhampuz, Bounty Detective, Bubbalex etc. It is even safer if the project you are participating in uses a payment system using btc, I remember if I am not mistaken new managers like SmallRabbit First time managing Amepay projects using the btc payment system in the signature section.
Escrow isn't everything, even reputable bounty managers are been used by scam projects too, you need to be in charge of decision making so don't rely on others, so your own research very well and accepts whatever happens later, not all bounty projects from bubbalex and others become successful, that's reality
