Thank you so much for posting this, @heiditravels!
It's a subject that's really been an issue for me as a pro-photographer for more than a decade. Copyright laws around photography are ambiguous as it is – the internet hasn't helped matters. At some point I had to just accept that people are going to do what they want, with or without consideration for intellectual property.
Lately, however, I've been looking into the use of blockchain as proof-of-existence. The concept sounds promising. I hadn't heard of Copytrack, yet I've been keepin an eye on po.et and have considered experimenting with Yours. Glad for the new lead!
