You see the point of this a lot in API design, where a company is like "okay we made an API but we limited it a bunch because we are scared about cheaters/bots/scrapers/whatever", while the things they limit are things a user clicking links can do in 2 seconds.
like, if your API doesn't provide me a follow_user() call, but the user can follow anyone by clicking one link?
Your lack of a follow_user() call is not going to stop me. I'm just going to click the link, automatically.
Having an API 1.0 doesn't mean API 0 goes away.
