Declined post flags give people warnings and can result in flag bans.
Allow recovery from flag hellban
There's a rise in both flags and in declined flags, as reviewed in these two questions:
Can we have some statistics on the potential change in rate of comment flags?
When is a comment hostile or unfriendly? (Educating newer users how to flag comments)
There's been a lot of discussion about what to do with rude commenters:
Can we implement temporary automatic comment ban on 'x' number of validated rude comment flags?
Can the recidivism system be applied to comments?
But little to no discussion to cope with people failing to understand how to use comment flags or abusing them altogether. I'm not sure many users are even aware if their comment flags have been declined (a UI issue). But a pop up message or ban, in whatever way possible may assist.
Certainly as a mod, it can be hard to track someone's comment flagging, it depends on who's handling the queues at that time. Without looking at a user's history, we have no idea how many declined flags a user has or when they were. A person persistently flagging another user (targeted flagging) does tend to come to our notice, but it's still reliant on keen observation.
Can we at the least institute automatic or manual comment flag suspensions for declined comment flags? Or an auto mod flag that a user has X declined comment flags (similar for users who have too many rude or unkind flags) so we at least know to go and investigate that user?
My only hesitation in asking this, is comments are supposed to be second class citizens and to implement this may require a bit of dev time for the network. I'm not sure how messy this will be on top of the teams current todo list.
To begin with, perhaps the team could implement the simplest solution until a better UX/system can be implemented? It would provide an easier way to moderate the sites and take the pressure off Shog being pinged for stats, to help mods work out if their subjective experiences are meeting up with the objectivity of statistics.
