For example, this: https://gis.stackexchange.com/review/suggested-edits/154910
It's just a minor edit "for grammer" to a question that is over 4 years old. I know this has been raised before, but it feels like an edit just to gain reputation/badges. And won't it bring the question to the top of the pile when nothing really has changed?
So I guess my question is, would it be wrong to reject minor grammar edits on very old questions? I don't see any benefit to accepting it.
