What projects should do, is define a reasonable bounty pool, and expect reasonable results.
Exactly why would they even promise something that they don't even have or couldn't deliver?
Bounty hunters are paid if the project is successful, one of the important things in the success of the project is promotion, so if the project is not successful one of the causes is ineffective promotion.Then you as a bounty hunter must also be blamed by them. do you think you have been promoting their project seriously ? do you feel the promotion you have done is effective ?
