This issue is discussed a bit in the linked post.
The situation is a bit similar to that for NSFW: if all content is not perfectly labeled, then is the tag worthwhile to exist at all?
And mods will abuse the system regardless - e.g. look at how often Lemmy.ml removes posts citing “rule 1”, despite that rule never anywhere anyway in any language stating that you are not allowed to criticize (or not support strongly enough?) Russia, China, or North Korea (or perhaps soon adding the USA and Israel?). Regardless of platform - Reddit, Lemmy, PieFed, Mbin, nodeBB, Mastodon, Pixelfed, Loops, etc. - mods are gonna mod regardless, and some will be better at that task than others.
Though it is still useful to have “rules”, and use them in communities, even if they aren’t properly implemented in all situations. The alternative being 4chan where anything and everything goes - not everyone is looking for that?
I guarantee you that Lemmy has for multiple years already abused non-AI content in a far worse manner: see e.g. the (non-AI) moderation tool santabot. Even so, Lemmy does not abolish the ability to post things, or to vote on it. i.e. the worst excesses of a thing do not preclude good uses for it. Knowledge that Santabot exists may encourage you to stop participating in the entire Threadiverse, but it does not need to? Systemically, the Threadiverse is fairly good, overall?
And now PieFed offers tools to detect AI content. I guarantee you that it will be abused, somewhere/way/when/how. Though at least now it exists, and can be improved? And we can be a part of that process too, by offering realistic suggestions to the development team, which demonstrably listens to and actively solicits such feedback all the time.






You could host your own instance (of PieFed, Mbin, Lemmy, Mastodon, Pixelfed, Loops, etc.) and then you’d simply be sending the user-agent info to yourself.
