it really hurt when I worked on the bounty program until it ended,
and the prize was not given to me, yes it was the most painful experience I have received,
but I am not easy to give up, I am still trying my luck at the bounty.
I know how you feel, i had the same experience, and more than once. For those bounty projects i don't get my pay, my method was blacklisting the bounty manager, maybe some are not manager fault, but i still don't want to work with them. I don't give up too.
Just don't give up. I like the way you blacklist these bounty projects. If I see scam I also give them bad merit too, I always tend to check projects and gambling sites if they are scammy in nature and I have been attacked here before because of these scam projects. It is best to give them a bad rating even if they retaliate and they give you and their minions give you a bad rating too. That is just how the system works around here. Don't give up and good times will come rolling on us.
