Did you ask them which part of

Your Information and your activities (including your payments and receipt of payments) through our Service shall not: ..... (c) consist of providing yourself a cash advance from your credit card (or helping others to do so),


it was not a violation of? They probably asked and were told to tell you anything to get you off the phone, so they could deal with the next yahoo asking the same thing. Then they gave you a name and employee number from their list of names to use and numbers to use. They will all get a good laugh when they freeze your account and tell them, no, Bill, number 4399876 told me it was OK.

They will tell you there is nobody named bill 439..., and you are in violation because you are providing yourself a cach advance, which as quoted above is clearly in violation of their TOS, and they are notifying your credit card company.

It's not worth it. If you get caught you will be fighting for weeks to get your account unfrozen.
