Mysterious New Likes

Hello, I’m pretty new to 3D printing but I’m a designer and I think it is definitely the future and has closed so many loops/made things faster for me workflow-wise it’s incredible. Just joined Pinshape recently and I have a handful of new followers who have popped up in my first 10 days, but strangely 9/10 of their profiles display a pattern, i.e. they have between 4-6 followers, but are following 300 - 315 people, have a super hero profile pic and always have nothing at all to show. Are these some sort of ghosts in the machine?
