We've seen an uptick in people posting dunks in here that belong in dunk_tank, as well as low-hanging fruit that gets removed from or isn't allowed in dunk_tank anymore. For context, rule 8 of dunk_tank:
Rule 8: The subject of a post cannot be low hanging fruit, that is comments/posts made by a private person that have low amount of upvotes/likes/views. Comments/Posts made on other instances that are accessible from hexbear are an exception to this.
There's a reason that dunks are cordoned off to their own comm, some users rightfully don't want to see reactionary nonsense all the time, even if we're making fun of the person who said it. /c/cth is a general-purpose comm but it's NOT for posting some random nobody asshole twitter user's bad takes, the absolute best course of action to take when you see that stuff out in the wild is to either directly shit on them yourself, or ignore them and don't give them more attention.
From this point on I'm going to be more stringent about moderating this. I get it, it's fun to dunk on the libs and the blue checks and the 
and that's why we have a whole dedicated comm for that. Any post that's obviously meant to be "hey look at this piece of shit, let's laugh at how bad their opinions are, upbears to the left and emojis in chat" belongs in the_dunk_tank. And any super low-hanging fruit doesn't belong on this site, period (see TDT rule 8 above). We have better things to do with our time than give unearned attention, time and energy to low-follower-count nobodies yelling into the void.
Thanks for your discretion comrades, stay sicko 
edit: as others have pointed out, /c/shitreactionariessay@lemmygrad.ml is a good place for any and all dunking content not allowed here. Post that ragebait to our comrades at the 'grad, they'll make good use of it. Also, per rule 9 of TFT dunking on fediverse users is still explicitly allowed so it's still open season on those in our own backyard.
I can't see it lasting longer than two weeks tops. The idea is that these types of post are too low effort in the first place. If users had to post them in a specific thread guaranteed to exponentially reduce views and interaction, they'd just decide it's not worth posting at all.
Counterpoint: Newsmega. The news megathread is one of my favorite parts of this site and it is very active even on "slow" news days. Obviously it's not a 1:1 comparison, but I think it illustrates pretty well that posting to a megathread is not at all a guarantee to exponentially reduces views and interaction. In fact, commenting to a megathread takes less effort than making a regular post, and that slight increase in the ease of making a contribution might make it more likely that people here will take the time to share some fool they happened to see somewhere else.
Well we needed a war to get the war/news-mega off the ground. What would a dunk tank mega need to become popular?
There's massive Drake slander that's happening right now with people digging up and rehashing all the times he has acted like a creep, so I guess that could work.
the trans mega got popular on its own so maybe it could be the same for the dunktank one
trans people are valuable and deserve community and built one, no-effort "look at this nonsense my friend's uncle said" posts are not sapient beings and I don't expect this tantrum to reach much beyond the current thread.
good
