You can't type "mailinator.com" in Facebook

I've known for awhile that Facebook directly bans signing up with a mailinator address (several of the alternate domains work - and more are on the way).

Interestingly, I commonly attend San Francisco & Silicon Valley entrepreneur events and I've met a few facebook people. In one instance, I had a fun jabbing match with a Facebooker who ended up being a friend. He assured me that Facebook will ban mailinator for good and I assured him I'll be working to get around that as a personal challenge :)

(I then sent a box full of Mailinator t-shirts to his office)

In any case, what I didn't know is that in Facebook chat (or wall posts) you cannot actually type "mailinator.com". It prevents you. Wow. Paranoid much? (Somehow I don't think "mailinator.com" is abusive as the message that pops up says - and note that you can type "mailinator" (without the ".com") which is apparently fine and dandy - for the moment anyway).

I did successfully create a Mailinator facebook page (feel free to become a fan!) and so far its still up. We'll see how long that lasts :)
