Which social media posting works best? (Patreon)

I mostly post my work on Facebook, LinkedIn, Instagram, Deviant Art, and ArtStation, but there are others too, like Steemit, CubeBrush, CGSociety, Gumroad, Pixiv and even tried Pornhub in desperation.  (There's a funny story about how their algorithm for checking fake accounts isn't working very well, at least in my case.)

I'm just wondering where you guys saw the post that made you join me here?  :) 
Happy New Year!
