Just curious as a noobie to the forum. Most forums have a "for sale" section. Along with that they also have various requirements to post an item for sale or to reach out to a member who has an item for sale.
Hopefully one of the forum mods/admins will see this question.
I think they just got tired of having to deal or just the possibility dealing with issues with sales. Someone gets scammed and then wants the forum admin or whoever to help out. Plus, with the nature of this forum, you are dealing with firearms, possible import/export issues, etc.
