This is far too technical for me but worth the effort on your part as you can expose the wrongdoers when it comes to uploads. I just unfollowed a couple of people today that I was blithely giving upvotes for and it turns out all they did was put photos or news stories I could have got for myself! By the time I twigged what was going on I had to go to Smeeitchat to find how to delete them from my feed list. (Unfollow!) I like the idea of freedom but sometimes it is abused and the people who work hard at Steemit (good post and good curation) don't get the merit they deserve. Thanks for this post - even if most of it is above my head!
