I was unable to post using the word Pro-zac. (Without the hypen)

Prozac? Weird.

Edit: HAH! Wow, that's weird. I wonder if they changed something since then.

Let's try...
Prozac

Yep, it looks like it is not censored any more.

I wonder if sometimes the host server just picks out a random "word of the week" that it won't allow. Now I'm going to see if it will let me write casino, which it wouldn't allow in the past.

Edit: yes, it let me do it. I previously had to get around it by writing cas+ino or talking about a gambling den instead of using the other word.
