If someone who has never posted, or rarely posted - contacts you regarding purchasing somewhat rare frogs ... well, the odds are good that person has been banned here and is trying to keep a low profile."Hey Pal, want this cool, rare frog?!?"
So please do let the Moderation Team know if a person like that contacts you offering somewhat rare frogs.
We like to keep the scum off of the site if at all possible.
Have a good day!
