I am also complaining about bots and I just wrote today about my doubts of the flagging system, I can still absolutely agree with you. The atmosphere in my opinion is good. The community seems to me to work pretty strong together. I think the best we all can do against trash content and spammers is ignoring. It's hard for some egos I know but even negative recognition is something worth for those people. If they won't earn any recognition at all most of them will give up after some time.
