Bounty is not free money, you do the work and people pay you the shares, the project spread out/ become more value, your share got more value.
So of course we have to take it serious as our job.
The most important thing is to find the potential bounty and it actually paid (as I saw many comments about running away bounty).
I strongly agree with your statement that the tokens obtained in bounty campaigns are not free tokens from our developers do the work of course it must be done seriously do not let us follow the project futile
