1. Think up a clever vandalism — something like the T-shirt pic is good.
2. Stick it on Durova's user page or Talk page.
3. Grab a screen shot before it's reverted (like within two or three seconds).
4. Send me the screen shot and I'll link to it from my
vandals page, with an intro sentence to the effect that Lise, aka Durova, is one of the least-liked administrators on Wikipedia.
Here is an
example that got Jimbo upset (he seemed to think that I was endangering his daughter, blah, blah) so I don't link to it anymore. I may go back to linking to it now that I'm rebanned anyway. It's an excellent piece of work, as you can plainly see.
If your vandalism is off-color I might not like it, so you may want to check with me first. It should be clever or funny, not dirty or overly insulting.
