Yesterday I was reviewing some edits and came across this user who was changing all occurrences of "pain in the ass" on stackoverflow to something like "difficult".
I think I reviewed 3 or 4 of these edits, some in questions already 4 years old. I must say I found this a waste of time and would rather review edits that improve posts content-wise.
My question is: should we encourage this kind of edits, or should we just reject these (assuming that the user will give up eventually in case all edits are rejected)?
