Actually, that's thanks to a well-known weakness in the FB apps API. It ends up allowing people to post a link to an external website, and then have that link automatically share that link on the person's wall and to their friends. The conclusion? Peter Kent clicked on the link when he saw another victim post it, and it was automagically spread all around as if he'd intentionally shared it. I see those things blow by on my feed all the time... always good for a larf at the sucker that got conned into clicking the link.
OH MY!
