So, to me it seems like self-answers here at Code Review are bad form. At other SE sites, if you receive answers that help you to the correct answer, normally you'll give those the credit and post your answer for your exact problem.
I know we can't control what others do and I have a down-vote button, but I ask because link removed a check-mark from an already accepted answer (not mine) to a self-answer.
Now, I'm not trying to call anyone out, but I wasn't sure if I'm correct in my assumption and whether I should comment to the user on what "bad form" is or isn't. The user doesn't seem to have a vast amount of SE history (2 months I think), and normally over on SU I'd mention something because I know a lot of new users aren't very familiar with the format of the sites.
So I guess what I'm asking is - what's the consensus here? I did see Self-answers that re-write code with little/no explanation and Self-accepting own answer when competing answers exist, but I didn't want to overstep my boundaries as a particularly (low rep) new user to Code Review, and I wasn't quite sure how a comment about that would be worded.
Sorry if this seems like a dupe, but I didn't see a canonical answer.
