Windows Live Messenger also blocks links ending in .info:

 if you send "www.visitmysite.info" to a friend, it will block the message entirely.  I also use Pidgin, so I'm pretty sure they (microsoft) block it themselves.
 

OK, I had to see if MS was as stupid here in their implementation as I expected...and I was right.

They block '.info' ANYWHERE in a message.

Even if it's, say, www.infoworld.com. Or myPackageName.InformationRecord. Context does not matter whatsoever.

::sound of head hitting desk repeatedly::

Well, there is .inf in both of those addresses. Although I don't know if .inf's can be used to create any significant amount of damage...

Now the real question is, does MS block www.microsoft.com ?
Edit: Anyone know any .exe<something> addresses?
