so now that I visited his page, how to I get rid of his supercookie?

could a grease monkey script automatically clean up the supercookies after they have been planted?

Good Q. In Chrome, you can add a block action under the 'Exceptions' list. You can add blocks for Cookies(includes HTML5 storage), Javascript, and Images (shudder).

Before you do that though, have a look at what info is stored under samy.pl. Nice to see Chrome list HTML5 storage and cookies etc in one place.

* I'm not sure whether the above is really effective. * Repeating this for N sites that uses this is going to be fun. There's always the whitelisting approach, which is available in Chrome too.
