This whole idea makes doing business with either company difficult and very risky IMO. I have used Google Adwords for years and got a permanent ban one day out of the blue - no emails, nothing. I finally got in contact with an AdWords rep that helped me get back up but the whole process took nearly a month. Imagine if AdWords accounted for the majority of my sales?
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.
I had signed up for a separate account in order to get access to their API (you have to have an MCC account to use the API which requires you to create a new account - ridiculous IMO). They make outbound calls to new accounts to assist in setting up campaigns so when that happened I explained the situation and he played mediator to get it back up. Normally I wouldn't suggest breaking their ToS by making multiple accounts but it's likely the only way to get them on the phone.
