Referring to this question here, which has gathered more than 100 upvotes.
It seems to me that the user accepted an answer that is not really an answer, over other better, more informative ones.
If I remember correctly the user used to accept other answers ( but I don't have the screenshots), then suddenly the accepted answer is changed to the current one, with apparently no justification.
If this situation allows to stand, it will mislead new users who don't know a thing about Quantum Computing. This is detrimental to this site and SE model in general.
What to do with this case?
