I've been wading through SO comments mentioning 'accept rate' and cleaning up where appropriate. But following the recent SE data explorer refresh, the number outstanding has exceed 5 000 and I'm not sure the query I'm using is catching most or just some of them.
I'd say around 50% of the candidates - perhaps more - warrant deletion. The problem though is the sheer number. I can only flag around 50 or so a day, and from September 2011 there are around 20-60 candidates from each day. Often a post will have a number of other off-topic or obsolete comments that need flagging. I can't keep up.
Flagging accept rate comments is quite satisfying - they are instantly deleted. So this need not flood the moderator flag queue.
I don't think a wholesale delete is the best solution - I come across questions where the comment thread is broken by a deleted AR comment. Better to review each post, and flag comments as needed.
Anyone care to chip in?
(I should add that I've worked through all the pre-September 2011 items matching 'accept rate'. Pre-September references to meta question 5234 still need review though.)
