Is it possible to enable/disable Disqus cookies through script?

Disqus is omnipresent through Internet. And it is tracking you from one site to another. It would be nice to be able to post some comments through Disqus on some website (by enabling Disqus cookies temporarily). So userscript would delete Disqus cookies and when script is disabled, cookies get stored just to make post on one website. Than script can be turned on again and Disqus cookies are removed when it tries to track you on other website.

Is it even possibly by userscript?

did you try to use Ghostery? I think this firefox addon does exactly what you ask for.
