Why doesn't reddit have a button where readers can 'vote' on whether a post is fake or AI?

There are more and more obviously fake posts or AI created posts. If I read 'family helps family' and now everyone say I am 'ruining the vibe' etc. it almost certainly is AI.

I think it would be great where readers can help others identify the suspect posts. The arrow up and down vote is helpful but lots of posts can be real and still voted down.
