Thank You, FalseImpression
Thank you for posting the link. Seriously. Thanks.
I went to the site and this is what it said to me:
This content has been blocked because it does not comply with the acceptable usage policy.
The request was logged.
So apparently that is the problem. For some reason my computer is being blocked while other computers are not.
That is the first sane and sensible response I have gotten out of all of this. It is something unique to my computer/server/network/search engine/whatever.
Hey, it sucks, but at least it makes sense.
