Weather people buy from the farm or not, If there is demand, there will be poaching. Look at ball pythons, they are cb bred by the thousands in north american every year, but still they are also imported every year in large numbers aswell.
Also Iv seen alligator farms on TV and they dont exactly look like the best places to be raised, with over crowded ponds and unsanitary looking living conditions. But thats just what i see when looking at the TV. There could be better ones out there.
