Well not to bore everyone, but these are robots ...or SPAMbots. Not real people. The Internet is divided into about 5 sections ...ARIN controls most of North America. Generally I ban almost everything outside of ARIN. However, they still get through. If I block a particular Internet host, I may be blocking legitimate board users. So, I don't care if I block one from China, but I do care if I block on from the US.
