Hi everyone it has been a long time since I have been here. I took a break from marketing online to focus on other things. I was amazed by the new security feature on YSM concerning credit card update where in your required to put the old card number before you can input a new one.

Is this full proof security? what I mean is what if you can't remember the old one, does this mean you won't be able to add new credit cards or debit cards?

or what if someone gains access to your account and decides to use a hacked credit card to do advertising with the use of your account?

Will YSM be strict enough to inforce this rule even if another person poses as you and requests help regarding the adding of cards?

Thanks!
