They thought this forum a money machine and this will make them rich very fast . And they don't even know or visit any other thread thread expect bounty thread .
Of course because they never really want to stay in the forum, just do the job and then expect some payment, even if they are already spamming. Actually, I won't be surprise if they themselves are not reading the forum rules before starting using their account, so they can easily break some rules.
Certainly they have zero future in this forum .
They'll not rank up unless they contribute and earn some merits.
