I was tracked by LE once through credit card use. You might avoid a large cash withdrawal, but you will have left a paper trail that can come back to you. Try to plan ahead and space out your withdrawals.

You might try looking into Bitcoin...some ladies, including myself will accept Bitcoin.  I also have taken deposits via PayPal or Amazon Gift Cards.  You can buy a Vanilla Visa Card or other Gift cards with up to $500 credit available on them and pay for the gift card with your Credit Card.

Many Banks will cancel a credit card or freeze your accounts if they discover you are using the card for adult activities.
