I'm sure everyone's seen such questions where an answer that's accepted as the correct answer has only 1 upvote while another answer with 7 upvotes is down below. Even worse is when the accepted answer is too long pushing the better answer even further down from the view. And the OP was last seen Dec 4 '12 so no hopes from him to change his accepted answer.
Should I flag the question and the mods will change the accepted answer? (I'm thinking not likely but not completely sure, hence asking)
It leaves me no choice but to downvote the accepted answer even though it's "illegal" and/or it makes no difference. (other than maybe the next time I come across it I'll immediately remember why I downvoted it)
