I have recently have been flagging comments (especially on my old posts) a lot; I flagged cca. 40 (30?) comments as obsolete, too chatty or not constructive in a spread of around a week. All but one got marked as helpful, until two days ago, from when all my comment flags I raised were declined, including one I raised to explain why they got declined.
This brought me to Meta, where I found that this behavior was already observed, and that a mod gave valid explanation on why having a "shotgun" approach to flagging isn't encouraged (at all), or even really super-helpful.
Currently my flagging statistics count 255 net helpful flags. That gives me a limit of 37 per day. From that, under 10 a day were used for old comments, leaving many flags "unused", and maybe even unusable.
I'd like to have the option of mass-flagging of unneeded comments, but sadly, every such flag needs to be reviewed be a mod - so doing this is actually just giving them extra work, on behalf of doing more important things.
Is there any way, or anything I could do, to keep this practice sustainable?
