I feel that, playing the card of your spiders were once illegal imported is just plain worthless and not worth bringing to the table at this point in the spiders hobby or ours.
They are here and we are keeping them regardless of how they got through the gates to start with.
The fact remains this, you will never stop the illegal importers at this present time, unless NATCON opens legal trade routes or rains the might of law down on the illegal imports, until that happens illegal spider will still be "breed" in SA for years to come. and RARE ones at that!
Even if you decide to be above the law an avoid buying these rare species there are 10 other people who will buy them without thinking twice.
The importers already know the money they can make, the risk is in the reward and at times it is a big reward for small amount of risk or a rap across the knuckles..
Importing of new rare exotic spiders is here to stay and have been imported at an alarming rate.
And they are selling them.
I often say to people that want new species of spiders, If you shout loud enough and posted it on enough forums and chat groups someone will import it for you.
But then again, they might have all been breed in SA, by a very awesome and great, wonderful person who we don't know of.

One of the next rare species to be "breed" in SA will be
Eucratoscelus pachypus or they just going to end up in someones collection pretty soon.
To bring something to every ones attention,
Some importers / breeders / sellers have listened to the public and saw the market for what it is and are selling RARE, never before seen spiders at never before, descent prices. shocked
But regardless.
