I haven't read this article yet but one interesting part of this is Facebook. You can join any number of groups on Facebook for specific plants and plant types and there are sellers there showing off some very obviously poached plants. If you enquire with them they are sometimes only interested if you are buying hundreds of plants at a time. I also know a handful of collectors who are old and like to collect who have bought from these sellers.
