Does anyone else have to deal with gym copy cats?

so what's going on is that i've switched to this gym since end of April 2017 from another gym, but some of members (always the same 3 girls and 2 guys) none of us ever spoke to each other, we don't know each other either but they'll always watch me and stare at me like i'm a TV while i'm lifting weights then they'll come and try to mimic the same workout i'm doing on the other side or near me but does it completely wrong with horrible form, no stability, hunched back, relies on momentum, rocking their torso back and forth, no full range of movement, and it's just so frustrating to see people work out like that as someone that's been lifting for a long time, even today near the end of my workout as i was finishing up with core exercises with a ab wheel, this African American middle aged man that i've never seen before as i don't usually go to gym around 2pm but was watching me while he does some weird exercise on the pull up bar, basically his legs was curled up and folded and he's just like swinging around with his arms hanging like a pendulum ball, and as soon as i was done with the ab wheel and put it back at where i found it, he comes and picks the ab wheel off the floor and starts trying to do it but the way he does it is like his butt is dragging his entire body back along with the wheel instead of using his abs, his arms were all shaky when trying to extend out, his back was hyper extended and he was constantly turning his head to look at me and i'm just like "wtf? o. O" in my mind.

so how about you guys, do you guys have gym copy cats? and how's the experience with your gym copy cats like?
