Sites hire social media specialists whose job it is to figure out schemes like this. Over 200 views for this thread, and (just) 11 Instagram followers so far. I wonder if the same person thought this up who thought up the Greenie debacle. I guess it really is all about pageviews for CC. People submit Instagram photos, then post on their social media account to get people to like their submitted photo, all in the hopes of CC that more pageviews to CC will be the result (with more advertising revenue).
Maybe the CC kiddies will play along, because I doubt any of the parent posters will waste their time on it!
