I've personally PM'd a very valid source long ago about Sarcasms validity. This person has blue stars, and knew him. This person verified that he existed and that he was the size he claimed.
A note on Sarcasm – Although he attacks a lot of people and talks a lot of shit, he is one of the main factors for this boards popularity. Ron knows this, and so do many of us who have been around a couple years or longer. He started the style of humor that is used here on a daily basis, and is the centerpiece to the squad. Like it or not, guys like Sarcasm make this place interesting and funny, and without them, this place would be just another boring message forum. Adonis used to be the same way, but now just pollutes the board with his ego.
