Could Please try to describe what is your criteria by choosing bounty to work on, it would be helpful I think.
Everyone has different criteria for choosing bounty to work on, but in general everyone is looking for bounty that he will join, if the information is unclear and not worth following, then just leave it, because it is useless to spend time on bounty that are not clear origin.
Yeah, because everyone are not experienced bounty hunters that's why they can't find out which projects are legitimacy and they will be get payment. Actually still now most of the hunters are newbie so that they go to join randomly without analysis. Even they unintentionally promoting a lot of shady projects which are looking really scam/fake core team. At the moment is very difficult to search worthy projects.
