Someone purchased services from me using Echecks on Paypal.

After one month, they claimed someone went on a shopping spree with their account and requested a refund from their bank. I lost $120.00.

The buyer used a Yahoo email account. Gmail does not list the IP addresses of the senders, so I have way of knowing his IP address.

Moral of this story
I'll never accept Echecks or checks unless it's from a trusted customer.
I wish i knew this before.
