So what do you do when you've gone back 15 edits,
reverted to a clean version, incorporated all of the "good" changes that have
happened since then, and the original perpetrator then comes along and adds his/her
"bad" changes again? How long are you supposed to keep doing that?
Well, until you get tired of it, I guess. You're not obligated to do everything, Zoe.
