I've heard of redirect scams, but I do not understand how they work.
It seems to me you would have to have access to the hosting account where the domain name servers are actually assigned. It really seems impossible that anyone would be able to make
www.ebay.com land anywhere but on the ebay server unless they work at ebay or hack the ebay host.
And given the volume of traffic that ebay has worldwide, it seems like some 2-bit Nigerian operation would not have the capacity to accept the traffic that a host redirect would cause.
I'm sure I've missed something vital. Dammit Jim, I'm a mechanic not an IT engineer.
