While all of these places are not 100% active I do try to update a lot of them. I mostly use FurAffinity but am trying to use twitter more. I cross post all of my art to Inkbunny and Weasyl. With relevent content being cross posted to e621(Furry), DeviantArt (SFW only), and Heantai Foundry (Nsfw only).
I payed for a Pillowfort code before they had to go into maintenance and I am about to join on Newgrounds (Again lol) and anywhere else people suggest I join.
