From time to time anti virus software will block a particular site, even LRH or the site I want to use is blocking me. I have noticed this after going to obscure firearms sites. Not saying anyone is, but I can only imagine the garbage malware that a P.C. might be dragging around if it visits something similar to a pornography site. In general The responsible sites don't mind if you give them a phone call and let them know that a particular hiccup is occurring. The 250 billion dollar a year question is why is China even allowed internet access?
