I got one cease and desist letter last year and it scared the living hell out of me. I stressed for a month over weather I was going to get an official letter from a lawyer on behalf of the company...lol.
Yes..I am a pussy.
I'm also never worried about being in a large class action law suit that could cost me hundreds and thousands that I don't have, so they'd most likely just take outta my ass. lolol.
