Any ideas for handling "tyre-kickers"?

By this, I mean people who stumble on a site, click around a bit, then wander off never to be heard from again. This kind of behaviour would play havoc with a Dom2 automatic registration system if it wasn't handled in some way.

My suggestion would be the standard "we'll email you, and wait for your activation before we consider you registered". Even then, you'll still get people who will jump through all the hoops, only to abandon the game almost immediately it starts. I know this from experience with other web-based games I've managed.
