Air Canada offering a refund of tree fiddy.

What possible use is that?

I've noticed "has this sub gotten more right wing recently?" posts reaching the top post of the day in the last 6 months or so. r/norge and r/unitedkingdom being examples. You can automate bots that change a subreddit's consensus on certain topics by bot-spamming threads pertaining to those topics, especially in the first hour of a thread going up. I don't know if that's happening, or if it has more to do with the Reddit protest that saw mods abdicate their positions last June and new mods being responsible for the change... but it could also be a bit of both.

Negative examples are often just as useful for training an AI as positive ones. And it all depends on what you want to use the AI for. A moderator bot, for example, needs familiarity with the whole range of user responses it might see.

A redditor bot is a viable example of a forum member bot.

IMO, I don't think it can drive topics, but it could make things controversial.

Marketing to terminally online people maybe?

Entertaining puns and pointless jokes.
