It was the same reason that was provided in this case. A handful of people (in private it seems) had issues and UNAs kneejerk reaction is to fire away at the ban hammer, thus puzzling everyone as is being done here, round two. This is going to ultimately scare off would-be third party devs.

Can you blame any new dev being scared to come here? One complaint and your account/work is just poof, gone. Meanwhile the devs at UNA can freely ignore you for weeks on end, and act like nothing is even happening.
