Recently, I've been going through exiting topics on the SQA site cleaning things up along the way - marking "thank you", "it works", "you are welcome" or "good answer" type of comments as "not constructive" (apologies if it was too many flags). I've been doing this according to the StackExchange's comments policy, specifically:
When shouldn't I comment?
Comments are not recommended for any of the following:
Compliments which do not add new information ("+1, great answer!"); instead, up-vote it and pay it forward;
But, some of the flags were declined, even though they fit under the "When shouldn't I comment?" category. Note that I admit that some of the flags I raised were declined correctly - for instance, some of the comments, even though are "chatty" were a part of the context and had some value - in this case, I've flagged the comments mistakenly.
Following the Should +1 and thanks comments be a declined flag?, I've decided to bring it up here on meta. Please let me know the reasons for declined flags and advice on how I should think about flagging on SQA. Should I better use the "other" flag reason to better explain why I am flagging?
