Failure to provide a disclosure after using the tag would mean removing the post. It could be locked, but I would have to assume the majority of the spam-type postings that happened to make it past the rule 7 criteria are the ones who will not provide the requested disclosure. I think it makes for a good filter this way, but please comment if you think otherwise.

Sounds reasonable to me!

I think the major choice is for y’all (the mod team), as enforcing a tagging system is going to increase the moderation workload.

I have no recommendations for a bot.

…You could use an embeddings model for a little extra automation though.

This is a pre-LLM thing, but basically you could feed a script new untagged posts, use a embeddings model to compare the text of their bodies to a keyword (“AI”?), and spit out a number as a rough “similarity” metric. If it’s above a certain threshold (eg if the post seems AI related), send a message to the moderation team to check it, or maybe even post a rules reminder in the comments.

And FYI, embeddings models are tiny, so it doesn’t need extra resources to run or anything.
