I know if it the baidu spider and not the full string, hence my <off-topic> bit, but it is a pain in the rear why it would require 88 spiders and more on occasion to index the forums.
Problem is despite a comment already in another area to block/restrict baidu nothing appears to have been done. But a user can't check the robot.txt file, so I don't know if that may have been modified, if so 88 baidu spiders ignored it (now Baidu = 100 of 109).
