We are not going to unban anyone who was previously banned, that's set in stone. We are considering cleaning the slate for users under 5 previously, but I still don't like it. If I had 1 infraction previous to this change and still had 1 after, I would understand perfectly and agree entirely with it. I think most people are just too proud for their own good and will argue every way they can, be it logical or not, in order to clean their own slate. I don't buy that in the least.
If every other staff member wants to clean the slate, then by all means. My vote is solemnly against it, though.
