If you look at their history there is a Pumelo plant shipped to the US & I'm sure quite a bit more. It is pretty obvious this is not a Key lime as well.

If you look at the buyer, they are in the US. Real good way to spead disease from that part of the world.

The buyer :

This is one case I actually feel sorry for the government. They have a lot to keep up with. USDA will contact the buyer.

The first link is seed not the plant.. different set of rules
The second is clearly a Federal Violation unless quarantine is set at receiving.
I would think that the USDA would contact eBay and suggest eBay monitor that type of activity.

Turtleman, I would also think so. However, the USDA did not do much, and is still not doing much, about the small citrus trees being sold to tourist at Florida airports. - Millet (565-)

i wonder if non-government people can inform ebay about illegal activity and have listings removed.

probably not.
