If you require bounty spammers to have a higher rank, they'll spam other boards to fill up 30 posts and earn Merit. Please keep them isolated on the bounty boards!
They need to receive merits to get higher ranks and that is not so easy if someone is shitposting spam everywhere, and they will certainly get reported sooner or later.
Sure, they'll get reported, but if hundreds of Newbies start shitposting the tech boards hoping to earn some Merit, good users will abandon those boards too.
you can't force newbies to stay isolated in bounty boards, unless some rule change happens.
I have nothing against Newbies on the tech boards, but they should be there for the right reasons.
people should generally avoid participating in any campaigns that don't pay at least partially in escrowed Bitcoin.
Most people do

That brings us back to the the many alt-accounts that a few people use to earn from spamming.
