There's no post API and all sharing is done manually so spamming anyone with G+ is impossible unless you actively use it.

That's a little naive. Of course there's an "API", it's what your browser uses to post something. Just because it's not designed for automated programs it doesn't mean it can't and won't be used.

Yeah, too true. A quick strole through the internet "freelance" boards will show that there's no shortage of people looking for comment bots for all of the major platforms.
