What is HD? - Technically it means a resolution of 1080×720 or higher. We’re somewhat lenient, when it comes down to it, but will become stricter as more and more true HD content comes online. Shows should have more than 90% HD content (occasional non-HD videos mixed in is OK), in order to be marked as HD.
How Can You Help? - Just tag stuff that is obviously not HD. Our moderators will check out the stuff that gets the most flags, and if it’s under the minimum requirement, we’ll pull it out of the HD section.
