> If by "AI Slop" you mean
It sounds like you're taking this the wrong way.
My point is: they have problems with people posting too much AI slop. Native speakers, or even proficient speakers, (well readers) can tell the difference between ai slop and non-slop. So they could at least in theory know if the content they're about to post is slop and change it.
Non-native speakers cannot tell if the thing the AI spit out is as articulate as they were in their nature language, or if it's turned it into English slop.
Then it gets posted to reddit. How does a reddit mod differentiate <someone who just generated slop and posted it> from <non native speaker who used AI to write in English, but ended up with slop since they can't very the result>? My point is that you can't differentiate the too, certainly not when the first group can claim their non-native speakers. So the only workable option here is for non-native speakers to post in their language and for the readers to translate on their end. This, mind you, is how several social media platforms already work,
