Shitty thing SE'ing new or personal sellers in general and even more so by leaving them negative feedback.

It's not, they don't pay a penny to the game developers, so they are the ones ripping the developers. Also, they have hundreds of these keys, so their losses are very low.

Ok that I didn't know.

Regardless receiving negative feedback when you are selling a working product sucks, especially when you are building a new account.
One negative feedback in the beginning reduces your chances of getting sales significantly and it takes a lot of positive feedback to get your feedback % to look good again.
