not true friendo. If you are truly efficient or skilled you can easily become relatively successful to successful on Artstation. I posted an efficient character with nice lighting as one of my first Artstation entries, and got dozens of likes on it and new followers. On the same topic I uploaded quite a few assets and props with sheets and got new followers again. This was with no outside promotion to the Artstation link.
Do know that Polycount is a way to receive true adoration from "followers" and you can gain popularity there. You just need to be skilled in your art, render out nice screenshots (marmo or vray, etc), and give nice presentation.
I am not saying you are shit my friend, I don't know much about you. But Artstation isn't broken and I noticed that good renders make a world of difference. Have you attempted to use Polycount and etc to promote your renders?
