It's more complicated than that.
The asians sellers sends a hell of a lot of boxes every month to the USA, Europe, and wherever. There is a part of the boxes that are seized, but on the seller's side, there are no legal risks really - a tip and that's finished - second, the sellers are making so much profit for each box that goes through, that the 'lost ones' are nothing.
Of course, when one box is seized, the complete network is watched, however in China, there are many networks, maybe 20-30 different ones, using many different sending companies and agents FedEx, DHL, UPS, etc... It's a hit or miss.
Generally, except there has been a physical informant that went to the Customs of the USFWS, nothing happens. And for sure, even if the authorities watch the forums, they do not care that much. There are many possible pretenders, many small size shipments, etc...
The thing being that if you ask the sellers in Asia 'everything goes smooth', but based on Kaichen that I happened to know, the rate of seized boxes per year is about 15% on her shipments. She does not care, because she earns far more than enough with the remaining. But the customers are in deep, deep **** afterwards...
Eric, your suggestion is in fact a very bad idea. If a hobbyist gets a box seized, and the box was supposedly for him, he gets a fine, and some problens. If the hobbyist ask a third part, or delivery to the neighbors, etc... it becomes far more criminal, it's like a mafia network, or a 'smuggler network'. Alone, you can loose your plants.
If you involve third part, first they will speak 99.999999999999999% of the time and give your name to the customs, second it means that you really know you do something illegal. Last, it makes a network.
