Depends on the bot and its target subs. Some subreddits are set up to restrict posting below a certain karma line, so bots aimed at those will do stuff like posting to their own profile—to get around, say, a moderation tool that’ll auto-ban accounts that post in “free karma subreddits”—to build up the needed karma to post wherever. Those are the ones I assume @Kay_Angel is thinking of

But, a bot that’s aimed at a less restrictive community wouldn’t need to jump through the hoops so would work a lot more directly.
