It does not constitute hysteria to notify eBay about an obvious fraud. Especially, when you turn out to be absolutely right!
Now it may be LIKELY that it's a fraud, but until the evidence is examined... they can't call it a fraud!
The person that makes the purchase is the only one that can say if they got scammed or not. So who are all these people calling "fraud" when they have no idea whether it is or not?
Someone's obviously worried about something !
