Here is a link to some more info about range blocks (what LightHouse38 suggested). You just want to be careful that you aren't blocking more than the user's range as that will prevent other users from editing as well. As with anything, there are ways around even a range block; but it can still be useful.

Sure, some users might give up. However, others might think they just aren't doing enough to get noticed and do even more vandalism. You can't really predict what a vandal is going to do. Plus, to do that would require storing of that information, then checking each time the page is rendered to see which edits should and shouldn't be included. It would definitely impact load time for everyone and Wikia probably wouldn't like you for putting such a demand on their servers.
