Pardon my interruption here. If we are going to sue every mother fucking plagiarist of photography and meme, then I am sure as hell there will be a legal congestion given the abundance source of this stuff circulating on Facebook, Twitter, and Google + being re-posted without legal permissions whatsoever.
The diff between those sites and steem is that money is involved in steem. Monetization is happening here. Compare steem with monetized sites like youtube not demonetized sites like google plus or twitter.
