Any one has a solution to make this stop? if developers can't keep their promises even when they raise fund successful why needing how help to create awareness then?
Go to Reputation/Scam Accusation board to report these scam projects you mentioned. There could still be time to resolve this even if almost 2 weeks had passed.
You can't just complain here and expect people to exterminate these scams right away.
I was expecting to read about project development when I read the title and not a bounty related concern.
Anyway, the best thing for you to do is make your case in the Reputation or Scam accusation board. Do you have enough proof that they have ignored the hunters? Nobody can actually solve the problem other than the bounty hunters themselves. Do not expect anyone or the forum to do things for you.
Make a good case as I said already and/or create a flag against these projects you mentioned. Do you know how to do that?
Me too. I was expecting for a newbie asking for an advise to help him avoid scams.
