I need to spill my guts out!

I feel like my main point hasn’t been proven though. See this? Did Amazon give me this user’s credit card? No. Did Amazon give me this user’s address? No. Did Amazon give these details to the seller of the product? Probably not.

Same thing.
Do sellers on the marketplace really want any of that info? Probably not. Do they need that info? Nope.
On epic’s end -> Purchase is tied to account. If payment doesn’t clear, or a refund is issued- access to ____ is pulled.
User requires support. Seller can query the user’s status. “Hey, does this user have access to this pack (can only query packs you sell)” would be more than enough.

And if sellers are going to attack people over ruining their business, surely they realize they can always recover from one single review as long as they don’t hunt down the person who left a review?
And buyers can certainly go on a vendetta against sellers. After all, it’s simpler to be able to buy rather than sell (as it should). You can hide better as a content consumer anyway.
