Better spam control and author authentication needed
Comments and discussions under the videos could be very useful only if they are kept free from spam. Spammers often post links and ads. One way could be to designate some long time or serious users as moderators.
PS: In case you start such a program, I would love to help with moderation of content
Thank you for the feedback. We are continually battling spammers on both this feedback site and on mruniversity.com. We haven’t gone the way of community-based moderation yet, but if we do so, we’ll let you know! Thanks for the offer.
