AFAIK he's permabanned for repeated streaks of trolling, breaking the 24 hour bump rule (consecutive posting) and ban evasion. If you have other questions related to it, ask.
Please quote his troll posts if possible. This is interesting
You could just go read some of those last few posts. Keep in mind this is a guy that at one point asked the mods to ban or disable his account to make him stay away. I think that was the anonymint one. Then he came back later with I think at least one other account prior to the iamnotback though I can't remember what that one was as it was well over a year ago. He has some inciteful things to say at times if you can strip away all the nutty stuff but much of the time he just comes across as a raving nutcase. Some of the stuff he's said recently, like how bitcoin was about to crash (I think it was over a week ago), how segwit had been defeated on BTC and LTC, just makes it hard to take him seriously and in the case of the LTC talk, like he was simply trying to pump LTC for his benefit
Edit: Had a look. This was one of his other accounts after he had them shut down anonymint.
