I'm still thinking out some of the issues for my own potential SMT for my social network. One thing I am quite clear about though is that I don't know of a better way to handle the issue of copyright than by using media fingerprinting as Youtube and others do. When I looked into this for another project a few year ago, I found it was necessary to pay for access to fingerprinting databases and technology since the cost of developing a custom solution would be prohibitive vs. paying for a license.

I appreciate that for many, the idea of copyright policing is counter to anarchistic principles - but I don't really see how the network can be protected from litigation without it. I wrote about this in some detail with regards to steem, not so long ago.
