There's quite a number of consistent offenders that cannot bring themselves to marking answers as accepted.
I personally always comment on that and do NOT answer the question, regardless how trivial it is.
The reason why these users don't change their ways is because to some SO'ers, rep is everything, so clearly, just displaying the accept rate is not working.
There really should be a mechanism where if you have lower than say 5% accept rate for x amount of questions over y amount of time, there is some kind of associated 'punishment'.
- You cannot post a question, until your accept rate improves above the set threshold.
- Question can be posted, but no one can supply an answer yet until accept rate improves.
- Question can only be answered by SO'ers with say < 300 rep, so these new comers get an additional benefit to catch-up on some rep.
Does anyone have any other ideas on this?
