Everyone gets that 1 out of 100 buyers that are just too obnoxious to work with. (They want excessive customization, blame theme author for everything, etc)
It would be nice to get the ability to ban these kind of buyers from our items.
Additionally, it would be nice to show this on user icons as well, so we 'll be warned about obnoxious buyers that are banned from other authors.
Envato, this is a two-way street. Buyers get reviews before they get to work with us and we should get some tools to filter out certain kind of buyers.
