True, I've done this for sites that had really slow loading webfonts and/or remote css pages. Although we really can't say what it looked like without the rest of the page contents. I don't suppose anyone has a page source dump.

I wonder sometimes if this sort of activity (honey pots for autobanning) angers people because they feel they have a right to script the site or if they feel poorly for "falling for" the honeypot. Clearly it generates some emotion though.
