I used to see larry laffer on Scott Matusow's radio show related to stocks and investing. First, he seemed ok and after people started to know him, openly discussed being thrown in jail for stalking an ex girlfriend. He was asked what he did and he said "nothing," claiming he just wrote a couple letters. Obviously, there is no way you would be in so much trouble for only doing that.
THEN, after one of Scott's stock picks went horribly bad, larry tweeted at him relentlessly all day every day bashing him for the bad pick that created many people to lose money. Although I could understand him being pissed, it was lunatic level stalking until Scott blocked him. Then, it was obvious that other accounts stalking Scott were him as well with the same behavior after being blocked.
Safe to say, his behavior doesn't surprise me.
