According to my notes 18.104.22.168 - 22.214.171.124 has a history of bad hits. I have a note that it may be a server farm or may be static business IPs but either way it's blocked.
I take it the rows of +++ are where you have obfuscated the original pagenames? The 403 rejects the visitor - did you do that deliberately or was it generated by something out of your control?
I consider any firefox earlier than 14 to be a possible fake, with the exception of 12 which is the last version that Windows 2000 can run.
I haven't considered google to be a responsible SE for a few years now - it often returns gibberish, as I understand it. Try ixquick - works for me.
