The sound mods are not biased! I don't know why you think this. As I said, they are not all seeing and do miss stuff or make mistakes. Flag or make support tickets about the submissions.

They trash all the copyrighted stuff they see. However they are not all seeing and if it's very recent >24 hours then it may not get taken down immediately. If you flag copyrighted sounds it points them out to the mods as well.
