Okay, so I was looking at a few websites that had stolen things from my websites, to see if they'd removed the material. On one website, the pages where my stuff was had simply been unlinked from the mainpage (and the site had subsequently moved, sans the stolen things). Looking at those two pages with Internet Explorer (no Opera on this computer), I noticed there was, guess what? That little "no right click" javascript.
The javascript alert window said, "Seja criativo e faça o seu!!", which in Portuguese (even if I don't speak a word of Portuguese, I can still understand the meaning) means, "Be creative and work on your own stuff!!"
I have not the words. Really.
If I'd noticed before, I'd have wiped the floor with the little shit, and not only threatened to get her webspace and internet connection pulled, but done so for real. ><
