I post Slugworld on dedicated Tapas, Tumblr Webtoon, SmackJeeves, and Facebook pages. Also I post them to my Deviantart, but only when I've finished a story and upload as a single file.
Fantastically False Facts only has a dedicated Tapas and Webtoon page, but gets uploaded to my personal Tumblr, Twitter, Instagram, Facebook, and Deviantart accounts.
Of course I also post them both early on my Patreon, but that's really a non-issue.
