Look at whos online. 10 members 100+ guests. Look at the list and the Baidu spider dominates. Can we limit the number of Baidu connections. Its not like we have a plethora of Chinese members. Probably less than 1% of members are Chinese and its taking probably half the bandwidth.
If it were me, id just dump the Baidu spider altogether. In fact, if I could, I would limit it to 10 spiders of any type on a first come first serve basis and 403 the rest.
