Recently, most of the forum bandwidth was killed by Baidu Spider and others.
At every single time there were more than 100 spiders scanning thinBasic forum.
I've installed an anti-spider module in order to reduce this situation to a normal one rejecting scanning from spiders having too much process running at the same time.

Hope this will release web resources to humans.
