It make sense, that's guys from 1990's bookmarks, so excluding the too young guys who learned internet from tubes since day 1, or who otherwise moved away from tgp's.
Actually oldest sites are very good for cam sales too, for example
domai.com it is an 1997 ccbill site which sends us traffic from both free area and member area (via plugin) and despite you don't see its banners or ads or even stolen content often around anymore, its traffic is more stable and good than any recent site we buy from or partner with.
In fact the real new business it comes from the past.
