Thankfully eBay UK have resumed there normal practice! After receiving information from a fellow pornography seller, here is a cut and paste from the message that they received from ebay:
Thank you once again for writing eBay. My name is [removed] and I
will be happy to assist you today.
Yes, as long as the magazines are pre-1980 and no nudity is show in the
image you can relist them on the site. Please state in your listing
description the year the magazine was published.
Thank you for your understanding in this matter.
I felt, after reading this, that I could list some 70's mags on ebay UK. So I stuck one up, but within a few hours its been removed. Thats the really great thing about eBay. They are soooo consistent!
