there is not, but you can impose the limit by having them edit, which results in a "Welcome to this wiki!" message being posted on their wall. Once it says "posted an hour ago", you're greenlit.

The difference between editing amounts and editing times is fairly straightforward: time

In one example all you did was momentarily inconvenice a troll for roughly 4 minutes while they make a new account.

In the other, you force them to wait an hour/day/whatever you want until they can join.

Which would you, if you were a troll, be more likely to harass? A person who gets angry every time you bother them, or a person making you wait to annoy them?
