Another case: SF-Based Yardsellr uses Facebook as the only authentication platform and not only requires all users to use Facebook in order to use their application, it is also very tightly integrated into Facebook Pages and other areas. If Facebook auto-bans their application their entire company shuts down until it's resolved. Imagine the losses.
I've been very concerned with businesses basing their livelihood on top of existing platforms like Facebook or market places like AdWords. It's easy to overlook how quickly your company or application can be banned - especially now that the bots are coming out to play.
This isn't to say that removing the bots solves the problem. The real problem lies in the lack of control you have over your business processes when you build something on top of existing platforms. However, this certainly exacerbates the issue and makes it all the more volatile.
Except that I've never used it but a few times, and never violated the terms.
The rep refused to tell me what was violated and said this matter was closed.
How did you get them to unban your account?
