They shouldn't get a "second chance" after a permanent ban. That invalidates the entire point of permanently banning them.
Perhaps
I made an alt before the system changed, Badspot approved my account then Ephi blew the whistle on my about a month later and exposed my alt. Miraculously, I was allowed to keep my account; I did run into 2 temporary bans on occasions, both inside messy drama topics (aren't they always). But I was allowed to stick around.
I was perma'd in 2008, perhaps the time gap was enough for him to not care? That or he was implementing the system and couldn't be bothered denying the account when I'd make one later anyway under the self-activation scheme.
