Facebook even censors pirate bay links within private messages between you and friends iirc. They don't block select other torrent sites though. They're a bit odd like that.

Some more info http://torrentfreak.com/facebook-blocks-all-pirate-bay-links...

Looks like FB blocks links to torrent detail pages on TPB. Best I could do was post a link to things tagged with JSTOR (there's only one): http://thepiratebay.org/tag/JSTOR

I am trying to post a link to the PirateBay page in my personal news feed.

I get a message about abusive content.

Me too. I even tried to share a link to http://thepiratebay.org/torrent/5023425/Holy_Bible%28s%29_-_... but it was denied
