A digital good is a good that does not have a physical nature,in my opinion website,domain name,apps, and all other virtual items have to stay in the digital goods section ... so we can create a sub section for all other objects.
I don't get it. What are the "all other objects" that you mention?
All the threads that don't belong in the Digital Goods section are those that would be removed anyway after reports - for example, a physical item thread.
Moreover, you should show a significant portion of threads belonging to a single type to show that a need arises for another subsection. That's the deal with Invites & Accounts. I'd say that if you can find that 40% of the threads belong to your "all other objects" subsection, then there may be some need for it (though the creation still has to have purpose: it can't be "domains" or whatnot)
