I think part of the problem is the amount of copypasta right now, so when people see an article like your excellent "Are You A Slave" article - they may assume it's not original.

3 "solutions" come to mind.

1 = Spammers getting their asses kicked. The fight back has begun. Behind the scenes I've seen some very encouraging developments.

2 = Making your posts more personal/timely so they stand out as being original. Probably a few ways to achieve this such as discussing trending topics within your nichce, as well as perhaps using more personal photos.

3 = Get more followers. Easier said than done of course, but I imagine over time, if you consistently post unique, original content, you will organically develop a loyal following who will reward you. In fact, I'm banking on that happening myself.
