Hi,
That's kind of a blanket statement though.
For all you know these were wild collected burmese who have never been exposed to any other reptile pathogens.
It's not something I would have chanced but, without knowing even the basic facts, I'm not going to condem someone out of hand.
If I did I would have to condem everyone who takes in garters and corns at reptile rescues, gets them back to health, and then releases them.
