Not to mention that Al indicated what got him banned was not what he said on the forums, but likely what was said in PMs or emails where he attempted to plead his case.
Since no one besides Al knows what exactly was said there, there's no way anyone can argue that his banning is "ridiculous" or "unreasonable."
But I will say that yes, longtime members here should get a bit more of the benefit of the doubt. But that's also not some type of bulletproof vest that gives you unlimited leniency either.
