I'm not sure if a secret sightings section is a great idea, mostly for reasons already outlined in this thread. I do however, think that something needs to be done about the scalper problem.

I would propose simply that the same restrictions placed on the viewing of the For Sale section be placed on the sightings section. ie. you must first post an introduction. Once a member introduces themselves, we know a little about them and they become part of our community essentially.

So where does this leave the scalper? I would imagine that the majority of scalpers are fans to some extent, or else they wouldn't know what figures were in demand. At the moment, they're an unknown entity that's depriving the community of figures. Once they've signed up and put themselves out there by introducing themselves, the only difference between them and any other new member are their moral choices. Choices that I hope would be influenced positively by all the great members here.

It's not foolproof, but I'm sure it would have a positive effect.
