I'd favour a permanent ban.
Secret bans normally are permanent. They're permanent and secret.

If a troll registers another account, ban that. If he registers another, ban that. And so on. Sooner or later, even the most persistent troll will get the message and either leave or behave himself.
There's no easy way to tell when a troll registers another account; you just have to wait for the troll to do more damage and then ban based on the new behavior, after the fact. With secret bans, trolls don't bother to register another account. They just go away of their own free will.
Another subtler technique is a "slow ban," which just makes the site horribly slow for the troll account.
