here's how it works (i'm withholding names until it gets resolved, as there may be necessary legal action):

someone contacts you about something you have fs, requesting that it's shipped abroad (to another country); it's very urgent that it gets there soon. he'll pay you from his domestic ?@/?@l account, including the rather exhorbitant shipping cost. when the $ is in your account, if you're not quick enough to immediately transfer it to your bank account (and wait for the transaction to be completed), when you send him the tracking # and he sees that it's in transit, he'll reverse the payment, and you'll lose the $, and likely never see your item again, or if your lucky, you can reverse shipment, retrieve it, but you'll lose $ on shipping. if the $ made it into your bank account, you may be luckier, in that it might be illegal for the payment service to make an unauthorized transfer from your bank or credit card to cover their accounts. any $ now deposited into your ?@/?@l account, though, up to the amount which they consider themselves owed, they'll take to cover their loss.

here's what to do:

Do Not Accept Payment with your Online Payment Service until the issue has been resolved, as they'll use the finds to cover themselves, and you'll lose the money.

Do Not Use your Payment Serice to Pay Anyone until it's settled; they may revert your payment to someone else from your bank account or credit card to cover the negative balance with which they stated your account to cover what is otherwise their loss.

Never send Anything until the Funds Have Cleared into your Bank Account.

(and, Never Pay through your Bank Account- Credit Card Only- only they May protect you- Your Bank Won't, and Neither Will ?@/?@l.)

if you suspect that you're being scammed in this way, Do Not Contact the Buyer/Scammer- it will only tip him off.

protect yourself first- no one else will be (as) interested, or can do as much. Immediately Cancel Shipment of the item. keep in mind that though your shipper may not operate at certain times, that their stations in other timezones may be open. get an international phone card and tell them to halt shipment immediately. you don't want to lose your item to a scammer, and cover shipping (and further encourage him/them).

if you don't want to close your bank account registered to the payment service, At Least Withdraw All Funds until the issue is resloved; that way, if they manage to gain some legal access to your account, they can't take what's not there. notify your credit card company, close your account, or At Least tell them that you feel that your Card # and Security may have been Compromised, so to please Change your Account # Immediately and issue to you a new card.

as always, be careful, guys/gals.
