i feel like bestchange is forgetting who their real users are.
they currently seems to care more about their partners and keeping them happy than actually protecting the users who got them to where they are now.
they seriously need to fix the review system as it's clearly favors their partners.
You are not the only one who got that impression. It has been pointed out to them several times here, but they appear to be satisfied with the current status. In the end, BC does its job for profit, we can't blame them much for that. The only question is how long-term it will affect their reputation as a reliable service.
