I was thinking this also when I saw some thai football (or something) related posts in /m/cats. The sole moderator is @Jay, who has never posted anything. At all. And they are also the sole moderator of /m/iphone and /m/chicagobears.
I know there was talk of reclaiming a magazine abandoned by the mod like this but I think it really needs to be addressed soon, as currently you can spam anywhere quite successfully (like the drug post in /m/fediverse) and even with downvotes the post will be on the front page for quite some time.
I deleted my account and no longer browse there. I've only looked at posts for niche technical problems as a last resort. I was using libreddit or teddit but both those seem to have died, if there is any other way to view individual posts without giving them traffic please share it!
