What is gonig on with facebook?

Is anyone else running into random bannings from facebook? i asked my gf to use her fb account to help me advertise for my website. Things worked fine for a while, then i thought i could be clever and get the $100 using the VISA business network. As soon as we did that ,her account got banned! (The ENTIRE account, not just ads account). I am now trying to get fb to restore her account.
I have seen people advertise $100 coupons, and i have seen people careful to ask whether those are VISA ones or not. Apparently there is something going on. Could someone please explain what is going on. Thanks in advance
