I feel like the five star system is also problematic, because I'm also a decent eBay seller with a sizable amount of purchases/sales, and I could have an absolutely stellar transaction, which gets hiccuped by, say, a car accident, and I get delayed in a shipping response. When said person delivers feedback, even though I communicated with them, they gave me a four star rating, which is considered failing on eBay. Four stars on eBay will get the attention of eBay and the account at risk. I feel like it's the same thing that happens here, people just want to give out the five star transaction rating. I got hit with a few four star transactions, and eBay did me the courtesy of a phone call to discuss how I can improve my sales transaction better. -_-
