It was a link to some website that claimed Brian May is part of the Illuminati and that he killed Freddie in order to profit from Freddie's death. (I'm just going by what was in the original post. I didn't visit the website.)
It's satire. Satire that unfortunately suffers under the ponderous comedic device that Brian is an Illuminati. I think it might be the same person or people that used to do Dr. Brian the Wise, which was hilarious about 80% of the time. We Think You Should requires a lot more digging to find the brilliant stuff, but it's there in small quantities.
Sometimes it was worth it just for the tags. :) link
