Kill them all. With fire. Spare not a single one.
On a slightly more serious note; the problem is now twofold. There's
the userbox mess to clean up, and the mess it's made in the community
- ripping the oldies and newbies apart - to clean up too. I'm thinking
a bit of friendly re-education into what Wikipedia culture is might
not be amiss. Instead of stating, "you don't get it"; teach people
what "it" is.
