Email that yuneeq and I received yesterday:
We like to keep things safe and secure, including your PayPal account. To do this, we regularly check the activity on our customers' accounts.
We're not sure you're aware but it appears the My Cash has been used for deposits to your PayPal account, and then those deposits have been withdrawn.
The MyCash feature is for making deposits to your PayPal account for retail purchases.
If we continue to see this activity of using the MyCash with your PayPal account for cash withdrawals, we may have to limit or close your PayPal account.
