Ebay is guided by five values. They are:

Have you seen this list before? I hadn’t and I didn’t need to. Because, after 2000 transactions, I can feel them.  I find most people I sell to and buy from operate from these assumptions. It probably helps that I believe these things too.

When people don’t act in line with these values, the community helps them to do so. Or it makes it hard for them to trade.

Well done Ebay community!
