Recently, the my default answer display order was changed from "highest vote first" to "latest edit first" (probably due to misclick on my part). I had not been aware that that was even possible, and spent a number of days thinking that it had been a site-wide policy change. During that time, I noticed a certain behavior that seemed intended to exploit the "active" answer ordering. (I'm not calling out specific cases because I really don't want to turn this into a toxic politics thing. It would not help.)
Specifically, having posted an answer of reasonable size, the author was returning to the post to make trivial edits (adding or tweaking a word or two) every time anyone else added a new answer or made an edit, thus ensuring that they were always the first answer on the list. I find this mildly unpleasant aesthetically, but mostly it seems like a behavior that we are encouraging (indeed, it exists only because it is encouraged), and should not be.
It seemed like it might be worth discussing. Is there anything that could reasonably be done about this? Should anything be done about this?
