As far as I know it's against WS terms of service to link to conspiracy theory blogs written by anonymous posters. The site you've linked has been labeled a conspiracy theory website in the msm and a recent article in Time suggests the guy who runs it is outright creepy and a stalker who signed off emails to the author "How are the kiddies" and he was keeping watch on her apartment and knew who she had been meeting with in Perugia.
Also the guy who runs it apparently had the police called on him because he had been stalking a girl close to Meredith's age. He is 70 years old.
You might not know this but the poster who wrote the blog you linked believes the cottage was a





house with prostitutes working there and Rudy Guede was a client looking for sex who paid with drugs he'd just bought.
It's an insult to the victim that a site like that one exists.
