I'm pretty sure Reddit as a company couldn't care less it's a bot or AI posting so long as it gets people to upvote it. People say they don't like it, but they keep posting on Reddit instead of leaving.
You're giving a lot of credit to marketers when they usually spend a budget without care and then report they had x views/likes/impressions taunting that as a success.
It's a bullshit oriented industry with almost zero scrutiny.
