But what worries me the most is something else. These accounts have applied to subscription companies that have limited recruitment. Thus, they could simply take the place of another, more honest person.
If the guy was a shit poster, He will not get accepted on campaign no matter what he do. Sometimes bounty manager still accept user with negative tag as long as his post quality is good and reason for tag is not cheating or scam.
If the honest person is doing really well in the forum by posting a good quality content, He shouldn't be worry on getting spot besides that, If the ban evader is accepted instead of the honest person that you are describing, It just mean that his post quality is not good enough and even though the ban evader didn't apply, someone better will get his spot.
