Are you some kind of idiot?

What about people who leave immediate negatives because they don't like it arriving in 4 days when told shipping would be 5, incorrectly interpret an emails 'mood', or mistakenly calculate a 50 cent postage discrepancy all due to their 'selfish' self interest of trying to get an item at well below what anyone could buy it for wholesale at times?

Knee-jerk reaction negatives are actually part of the buying behaviour that needs to be rated as to whether it was warranted correctly or not.
