It came up in chat that one particular user seemed to be in the habit of:
Posting a good question;
Receiving good answers;
Posting his/her refactored code
as community answer, after adapting some things using advice from answers, sometimes with little to no explanation about what they did different and why.Subsequently accepting selfie answer.
Getting good amount of down votes from community, effectively moving the post down beneath the good CR answer(s).
Mod converts answer to Community Wiki answer as per site policy.
It's been said:
Malachi: that one should definitely have the checkmark moved to @vpn's answer, the user says that is what they used.
Mat'sMug: should they be deleted? or that would make us bullies?
RubberDucky: Posting a wiki answer "Here's what I ended up with" is fine, but accepting it? That's just rude.
janos: to me it's not about politeness at all "Click to accept this answer because it solved your problem or was the most helpful in finding your solution"
SimonAndréForsberg: would it be better to just leave the question unaccepted? What is the actual harm in making the self-accept?
rolfl: The bottom line is that it is not something that can be affected by us. The accept mark is intended for the OP to use as a special reward, and is totally at their discretion
I felt it would be good for this to at least be documented if it comes up more regularly.
