This is "negative feedback" for EBay.

Speaking of Ebay, apparently a scam on sellers is happening (aps if this
is old news). Someone bids way over the price wanted and sends a
cheque/check for it. They want you to use a certain shipper to ship the
goods to them ASAP. Apparently includes emails & phone calls from both
(purchaser and shipping agent) wanting you to get your act together.

Yep, the cheque/check is rubber.
