I don’t recall ever reading anything on the blog that would justify any lawsuit.
Virtually all of the information provided was public information, and then freedom of speech commentary.
The only thing that is jumping into my head is perhaps he purchased in one of the neighborhoods or homes he actually featured on his blog. I’m not close to anything of a lawyer, but maybe there is a no-no somewhere in there if some of his information was incorrect @ helped to lower the sale price based on false information.
Who knows. Heck if you can sue for spilling hot coffee on your lap… or for getting injured while breaking into someone’s house… why not for some comments on a blog.
