good point you make. A friend of mine was once working in a company where such a content filtering system wouldn't let freshmeat.net through ...
Still, I don't believe that there is any good solution around. You can never filter things correctly when you're filtering much, as many of us will know that have worked with their own, home-rolled mail filtering mechanism (yes, I have switched back to hand filter all the spam that comes in *sigh*). On the other hand you won't be able to introduce some kind of rating mechanism in a community like PM. Such a community is always the sum of the individuals (probably weighted by their activity) and this particular one is very professional - at least in my eyes.
If your info security would only block offending documents and not the whole site it should be enough for you, er? In the worst case you cannot follow a thread (which I experience in groups.google.com because of firewall restricitions -BTW) but if you really want to get the info there it should be possible to get access from another computer (home?)
Finally the nodes you mention are in the discussion forum and thus not absolutely neccessary for your use for professional development; you could be happy without them. OK, this is still a problem if the whole site is blocked. Could that happen to you?
you begin bashing the string with a +42 regexp of confusion
