There's a good National Public Radio story today (at http://www.npr.org/2017/03/11/519807763/activists-work-to-preserve-government-environmental-data) about activists working to preserve the accessibility of publicly available web-based governmental data that different presidential administrations might want to make harder to find (which is not illegal) rather than destroying (which is illegal). One of the things that historian Matt Price discusses is how to make sure the data is not changed in the process of sending copies of the data to different locations, and mentions that this problem doesn't effect, for example, the film Star Wars because of the number of its pirated copies (which seems dubious, but still). The story makes no mention of the BTClockchain -- which goes to show how far it is from public consciousness. (All day Friday I listened to a local NPR station here in Los Angeles and it never mentioned the SEC rejection of the Bitcoin ETF.)
Anyway, activists could hash web-pages, online databases, images, etc. and use those hashes to create brain-wallet address, send a fraction of a bitcoin to those addresses, and voila, they would have immutable time-and-date stamps for those original data-sets, to compare with the hashes of all the distributed copies made by activists.
