Well, sellers have no protection against false reviews, 30+ sales at 5 stars, 1 fellow seller buys something at a discount, then rates 1 star for packaging, without ever asking for assistance. Tried contacting them, no reply. Obviously a spammer smear. Contacted Mercari and got only generic replies. Ratings can only be improved not lowered. Sellers have to rate buyer before seeing their own reviews, expecting no issues I rated this terrible buyer 5 stars.
