Ebay is just the listing site. It's all individual sellers who sell the items and Ebay has no way to know if the items posted are real or fake. They do not have possession of each item to check them.
Look at the seller's other items. If someone has 5 iphone6's for sale then they are fake as Apple doesn't allow anyone to buy that many. Same with someone who has lots of the same designer/branded items for sale - Gucci wallets, Air Jordan shoes, Ray Bans, etc. But if they have 1 phone, 1 pair of shoes, 1 set of golf clubs, 2 video games, etc then they are probably real.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
