We have installed the post rating modification a while back to give users an extra option to leave feedback on quality posts. While at first the system was used as designed and well received as of late there are a growing number of people blatantly abusing the system by downvoting threads of certain users without ever explaining why. As we are primarily a discussion forum where people can agree and disagree with each other and discuss certain topics the post ratings were installed as a bonus feature not to replace posts in a discussion. Unfortunately it's costing our staff too much time on daily basis to deal with this abuse. Until we find a way to deal with the abuse we are putting the post ratings on hold and revert back to the build in likes system. We hope you understand this decision.
