I have changed the ratings system to stop abuse. No longer is it possible to down-vote everything and then three star your own maps. There is now only one way for a map’s rating to go now, and that is up. This should preserve the usefulness of the ratings and greatly increase the work-load of anyone trying to stuff the ballot.
Unfortunately all the legitimate votes were also lost. In the future if anyone does try and stuff the ballot I can reset the ratings only for that post so hopefully this situation will be not repeated.
I have also turned on comment moderation, this means for normal users is that your post may have to wait a few hours before your comment appears on the site.
Most importantly I want to say sorry to those who originally got behind the ratings, thank you for trying to make this site better and SMR maps more approachable. I hope you will be willing to vote your favorite maps again.
