No sir, I am very much not sarcasm.
But I am well versed in research methods and I know how getbig works. When sarcasm first came onto the scene, I did my research. Verified his name and hometown, and was able to find a pic of him. He knows. Personally, I think sarcasm is a funny guy and delivers some much needed humor in an increasingly controlled getbig. Sure he goes overboard, but we all do. Besides, even if he was my bitter enemy and called my mother a whore on a daily basis, I'd never leak his identity.
