I watched an SEO company take down a site at a conference

I was at a conference a few years ago where I witnessed an unprofessional act. The presenter was talking about entry level SEO practices (there wasn't much on during that time slot and I needed a laugh), when they decided to end the session with a live site analysis from the audience. This is where things went south, but let me set the stage so that you understand why I'm calling it an unprofessional act.
