Bid or Buy Rating system rigged.

The rating system on bid or buy are being rigged and altered to hide reviews from sellers an then only keep reviews from buyers. The buyers are allowed to rate sellers but sellers are not allowed to do the same, their ratings are being deleted when they have a bad experience with a buyer. So the rating system on Bid or Buy are false and do not reflect what is really going on, that is why buyers will have 100% positive ratings and sellers will always have a lot of negative ratings against them.
