I tried starting a business selling those 30 day WoW subscription cards as I came on to a box of them for fairly cheap. I sold most of them, then one person falsely reported me of fraud and that was it, my paypal account which had all of my profits in it was frozen and I never managed to recover the money. IIRC I had close to £300 and I never found out what happened to the money; I imagine paypal just took it as profit despite every buyer giving me positive feedback up until that point. I was considering starting a marketplace on Amazon last year as well with a friend, just selling basic Chinese made goods but it sounds like things like this are rampant there too, and honestly I'm seeing a lot of sellers on Amazon lately that are scammers, so I'm beginning to lose faith in Amazon as a consumer as well. If I'm going to try and make a business from selling goods online I would want to run my own ecommerce shop using shopify or something similar.
