Why? 1 year is plenty harsh as it is if this guy is a pro (i.e. making the bulk of his money from gaming), and I would MUCH rather he learn a hard lesson from this and then be allowed back into the community to hopefully influence others to not be similarly giant assholes than to just kick him to the curb entirely.
Just throwing people out for life doesn't address the actual problem with the culture that causes this sort of thing to happen.

It's better that he learns from his mistake than to just ban him outright forever.
