You could call it a specific request. There is a little bit more involved though, in terms of how I'm associated with them.
The sheer number of websites being accessed each day is staggering, so in terms of starting a blacklist or whitelist, even if only for SSL, if that is possible, would be a huge headache.
I realize that we're never going to be able to block all objectionable content, so we're just looking at ways to block programs like Tor that create bottlenecks because they send all their data over SSL.
