When I first came to SU, if a flagged a comment, it would vanish. Back then, mods seems to have a deletionist tendency towards flags. Nowadays, mods almost always decline comment flags.
But things went outright outrageous yesterday: I flagged two instances of idle chatter in the comment section of "https://superuser.com/questions/1206525/is-flashplayer25pp-xa-compatible-with-npapi". Both were declined.
To put it politely, something is definitely wrong here.
