i know of one guy who got burned by someone selling some f2 carpet x macklotts as a new carpet morph. you'd never know by looking at them unless you do scale counts or really know your pythons... there is also one very well known european breeder who had a 'new morph' on his site that were clearly a hybrid, probably f2 liasis or antaresia x morelia.

anyway, just a couple examples... but i think when it comes to australian animals, they are a disgrace and promote bad genetics in our very limited genetic pools.
