As per title, is there any way to prevent or discourage serial useless edits? I've noticed a string of them coming from the same user and because there's no way to contact them directly I can't tell them why what they're doing is not good, eg most edits are things like removing descriptive terms from the question title which is not just pointless, it's actively counterproductive.
I'm guessing it's chasing reputation points, I can't see why else it would be done. Most of their suggested edits are getting rejected but enough are getting through to put them in the top 3% reputation points for the week so far. I've rolled back some of the more blatant edits but the reputation points remain.
Should there perhaps be a cap on how much reputation you can earn per day from edits? Or restrict the number of edits allowed per day based on the number of edits which are rejected? My concern isn't that a user is getting arbitrary 'points' or not, rather that the system as it stands encourages and rewards edit spamming.
