I often see a lot of high rank members who answers repeated questions all over again
That's what I'm talking about. It's like all the replies we see in the ban appeal threads. The senior members keep repeating the same stuff: apologies don't matter, plagiarism isn't tolerated, a permaban means you can't create new accounts, etc.--and yet it's the exact same crap being posted by the people who got the ban. They just don't read.
While annoying in Meta, it's not that bad in B&H. This forum is notorious for hiding important information. Even the "unofficial" list of rules is not easy for newbies to find. So I'd say repetitive questions are to be expected and kudos to those who are answering them.
However all that bounty/airdrop/how-do-I-make-money shit should have no place in B&H. It seems to have gone down a little bit recently, not sure if that's due to reporting/moderating or just a result of the bursting bubble.
On the other hand, if B&H is moderated heavily then larger numbers of illiterate newbies would spill over into Meta and other places where we don't want them - e.g. when they ask something in B&H and their thread gets deleted. Not sure what the proper balance should be.
