As a rule, bounty participants often drop tokens of bad projects, in which they also participate as well as in good ones. And this is the main problem contributing to the spread of the scam and the overall clogging of the ecosystem. And unfortunately the bounty participants are the main spreaders of this. If investors don't invest in bad projects, they will probably be less likely to face the situations of dropping coins by participants after distribution. But of course, the bounty participants should not contribute to shit and scam!
