Mods could be stopping link farming.

They could be turning the sub into a healthy place for discussing music, instead of a cesspit where the same old songs get upvoted time and time again, and anything outside of what a handful of redditors deems "real music" is immediately downvoted.

They could be removing the daily "recommend me music, I like anything" threads that add nothing of value (these are banned under rule 8 but they're never removed).

They could be combating the racism that's prevelant on the sub any time a black artist gets in any controversy.

They could, at the very least, ban people from posting "who?" on articles about artists' deaths.

They could either uphold or amend rules 6 and 7 since there's hundreds of posts breaking them every week.

They could respond to modmail, or at least acknowledge to the community that they're doing anything to combat the shocking state of this subreddit.

They don't do any of that and despite clearly not caring about the quality of the sub, they also refuse to appoint any new mods.
