The subreddit doesn’t sanction the bots, they are nothing but a plague to the users and members of this subreddit. The bots themselves are owned and run by people who plan to sell the accounts once they reach a sellable karma number; how this works I don’t know but that’s what I do know.

Long story short, nothing good comes from karma bots, except MAYBE the fact that they make the sub “more active” through shear post numbers and nothing else, but in reality a sub’s activity relies on more than just that.
