It's a shame as it's a sad day when the game loses characters and becomes more mundane. I don't know what he did, apart from what is being stated in this thread, so I say this with that reservation, but perhaps a shorter ban and an agreement from him to apologize to the stewards he offended face to face and accept a suspended longer ban might have been a more sensible option.
It wasn't violence and we don't know what triggered his misbehavior, but we've all had an attack of verbals sometimes only to have deep regret afterwards. Also, he does get unfairly targeted by some stewards (Barnsley, Rotherham are just a couple that spring to mind) and even though that might well not be a cause this time, it might explain some frustration. Just sorry to see characters excluded for such a long time.
