I'm getting a large, organized scraping attack from China. Can anyone give me an idea as to how to block it? All individual IPs, no repeating aa.bb.cc., few repeating aa.bb. I cannot block by IP. I've narrowed it down to East China, so only half of the 1.4B are suspects!
UA is the same for all. it seems very common. The "3B143" seems unique but I get lots of hits on Google search.
