IPFS is a new peer-to-peer hypermedia protocol
This looks very cool, but I'm wondering about abuse.  I watched the video and did some followup research using Google and couldn't find anything covering how to handle abuse within IPFS.  While I'm sure there will be a lot of photos of cats and wildlife videos it seems that this solution would be ripe for abuse by the seedier regions of the web.  If I'm participating in IPFS how do filter for or stop illegal content from being saved and hosted by my node?
