ffha,

He got banned for his abusive posts (both trolling and personal attacks) and creating multiple accounts even after being informed not to do so while being temporarily banned. He was warned multiple times that a perm ban could happen to him if he didn't stop but he wanted to game the system.

Re his "contributions", most of it was just simple things garnished to look like he had done a huge contribution... I would advice people against using his stuff blindly and to check it all out before applying it..
