Back foul (but somewhat useful) spammer!

OK, to download the document by the academic at Nottingham getting crap for looking after the interest of one of his students who was arrested as a terrorist for reading a book available on a US government website, I had to log into evilfacebook and say yes, Srcibd can spam me and know stuff from evilfacebook.

I've now stopped Srcibd spamming me. How do I revoke their permission to look at my stuff on evilfacebook?

(You can - and probably should - read it without touching evilfacebook, but it's 112 pages long...)
