Here is an idea for vandalism. Find the last non-bot, non-ip edit. Verify that this user has been on Wikipedia for a while, has a talk page with no vandalism warnings (again you'd have to check the history for the last edit made by someone other than the user), and/or has made more than 100 contributions. Won't get everything but should be effective.
