This guy better be careful
I just had a quick scan of the site and found a number of potential problems, for him!
1. The Lowe's logo is used on the web site and that is a trademark infringement.
2. He makes statements of fact, when they should be more carefully worded as his opinion. Despite his declaration at the top that it is his opinion. "LOWE'S is nothing more than a corporate bully that attempts to pervert the U.S. legal system to stifle a consumers free speech rights.", is a statement, not an opinion.
3. He makes clear threats against the company and it's employees: "Maybe I should start posting cell phone and home phone numbers of the Lowe's folks that have made assurances and promises that as far as I know haven't been delivered."
Otherwise, I agree with "sucks" sites to express your opinion, and Mr Harkleroad certainly has the right to that. I think that he is crossing lines and stretching his rights on this site though. Posting pictures and describing the process and results is a great way to get his point across but using their logo, defacing their logo, making statements of claim and threatening to release private and confidential information is just plain illegal.
