I've noticed recently that the Evo admins are very happy to delete negative feedback at the vendor's request. This seriously bothers me because even if 5% of all negative reviews are scammers, good service and product will vastly outweigh the negative reviews.

2 days ago toyota had received a string of 9 negative feedbacks, and now he has 3 so it looks like this is true
