Ease up, Facebook

I was posting a link (to this rad Threadless shirt) to a friend's Wall over on Facebook and received the above message.

Steps to reproduce:
1. Navigate to friend's profile page.
2. Type them a nice little note, pasting in the link.
3. Press submit one (1) time.
4. Get your account disabled?

My guess is Facebook is trying to be too fancy for their own good with pulling in content from linked sites. They failed to get anything useful from Threadless (image or otherwise) and apparently the fallback case in the logic is to pop this error. Interesting.

Anyone else have a similar thing happen to them?
