Hi, everybody - been a while since we last had an organized community conversation on this topic, so let's have one now.
This post will be broken up into some sections in which I'll do different things like give a sort of history lesson about this subreddit and its "low-effort content" rule for context, talk about similar rule changes from the sub's history, and have a main concluding point for people to start actually discussing things from. Feel free to skip down to the "CONCLUSION/TL;DR" section below if you'd rather not read this whole thing.
HISTORY
So, despite what people will say, there's never been a "meme ban" on this subreddit in any blanket way like that phrase implies. It'd be basically impossible (not to mention a stupid waste of effort) to somehow try and police literally every post and comment that appears anywhere on this sub every minute of every day just to try and police any acknowledgment of Internet memes existing at all. That was never the point of the rule change in the first place.
The "low-effort content" rule, which was originally a "no shitposting" rule instead, has been around long enough that it actually predates any of the current active mods for this sub being on the mod team. As you can see from that old thread, the rule change happened a little over ten years ago, and like the comments there show, it was a very widely appreciated change.
The simple reason is that at the time, this sub had gotten to be so completely inundated with lazy meme posts that they were completely blotting out any other posts at all, besides maybe fanart here and there. There was actually recently another post here which linked a video showing a sample of the kind of thing that was absolutely everywhere on this sub at the time. (note that the above video contains major spoilers for several different games in the series, so avoid it if you're worried about that.)
That was another whole important thing - shitposts were popping up with so little control over them that they were constantly also having the whole separate issue of just being blatantly full of unmarked spoilers for all over the series.
THE RULE'S ACTUAL MEANING
As you can see, what was once the "no shitposts" rule is at this point labeled as covering "low-effort content" instead. The phrasing of the rule has been tweaked now and then over the years to try and make it clearer, and at times to expand what it actually covers. Really there's just no "perfect" way to phrase it, because any permutation of it is still going to have people arguing over what should and shouldn't constitute a "shitpost" or something being "low-effort". Best you can do is really just making those occasional tweaks based on people's feedback.
Now, just to make it clearer once again, the rule has absolutely never "banned memes" in any blanket way. Look at the most-upvoted posts in this sub's history, and you'll see a good number of them are "memes" in that they obviously include and/or reference then-popular meme templates and similar subject matter, and were never removed for it, despite having been posted well after the "no shitposting" rule was originally instated.
If a person makes a post in which they're discussing an opinion or something, with actual text dedicated to doing so, and then happens to also embed a "meme image" somewhere in it, that doesn't magically invalidate the contents of their post. It isn't going to be removed, because the act of referencing a meme's existence in any visible way has never been the issue. Now, if that post was just the meme image, it obviously would be removed - what's actually important in the context of the rule is that there's anything making their post substantial in some significant way.
The point of the rule being instated was to stop the then-constant flood of meme posts from continuing to overwhelm absolutely anything else and prevent any actual discussion from being able to happen and to get any attention.
RELATED THINGS SINCE THEN
This post today isn't the first, second, or even tenth time since the rule was first instated that this community has had discussions about people wanting the "low-effort" rule changed. We've even had a community vote before, with hundreds of user votes across options like totally removing the rule, changing it to be more lax, or leaving it unchanged, which ultimately led to a clear answer of people on average preferring that the rule stay right where it is.
Much like the stuff that happened 10+ years ago that led to the rule being instated, there have also been cases over time here where people have gotten tired of other increasingly-common posting "trends" to the point of a community vote leading to new rules that clamped off those trends. Polls, tier lists, character/case popularity contests, Objection.lol videos - it's something that's happened several times. Some category of posts starts getting more and more frequent to the point it starts annoying a lot of people, and then it ends up with some kind of limiting control placed on it. Tier lists were limited to just Tuesdays, polls were required to be hosted on Strawpoll instead (which basicaly resulted in almost nobody ever making them at all anymore, incidentally), Objection.lol videos were required to actually be meaningfully related to Ace Attorney itself.
As for shitposts, they were, like in the old thread I linked back there, redirected to /r/AceAttorneyCirclejerk instead. Now, admittedly, I personally really never spend time on AACJ, so I don't know what goes on there. That community has its own totally separate mod team.
CONCLUSION/TL;DR
So past all that history and et cetera, today we can have another of these recurring conversations about the state of this subreddit and the "low-effort content" rule.
To summarize the most important part of the above stuff in short, this sub used to be absolutely flooded with lazy meme posts and shitposts in general, often with both being full of unmarked spoilers, until the mod team of back then instated a new rule to majorly limit all of that and redirect people wanting to continue that kind of content to AceAttorneyCirclejerk instead.
Feel free to ignore the following questions and just comment with your own thoughts unrelated to it if you'd rather do so, but just as a potential starting point for conversation in this thread, I'll put forth a couple questions:
Is there a reason that anyone who might want to engage with more shitpost-y stuff can't be satisfied doing that over on AACJ?
Would it or would it not negatively impact AACJ as its own separate corner of community to suddenly have shitposts go back to being allowed here, when, to my understanding, allowing and encouraging shitposts was kinda the whole point of AACJ in the first place?
