NetNanny does the same for certain threads -- it's all a function of their filtering software, which typically operates by means of a keyword search, coupled with a database maintained by the service.

I was denied access to a church website one day. I used my password to turn off the monitoring software. The culprit was a frank discussion of human sexuality on the website but apparently one of the words used in the title identified the article as porn to the software.

Net Nanny infamously blocked the whole White House site because one of the kids' pages described Bill/Hillary and Al/Tipper as "couples." And in probably the most infamous filter fiasco, AOL banned the word "breast" amongst many others -- which shut down the legitimate and much-needed breast-feeding and breast cancer support boards.

Filtering software is fine, but it has serious limits. And I wouldn't trust any that automatically bans sites based on keyword, instead of making recommendations for a blacklist that have to be approved by a sentient being.
