13. Before posting a new episode check to make sure someone didn't just post it
This applies mainly to new releases from the subbing channels, but really should be done for any post. Just before you start the upload, check aba/abma to make sure someone hasn't started a post of the same _exact_ thing already. Of course, because of server latency (the time period between when a message is posted and when it actually shows on your server), there will still be some duplication of new releases, but at least make a minimum effort to reduce bandwidth wastage.
