I've been doing some research, and it seems DA's original tracing policy, and it's allowance of tracing, has been deleted / altered.
I'm still not entirely sure though.
I definitely don't really want to go back to Tumblr as an artist since Tumblr's system and community isn't really for me.
Furaffinity I've avoided for years, the community is also not for me. Weasyl is the same thing, it's just really Furaffinity 2.0 in my eyes.
I am however active on Twitter, I do enjoy posting on twitter but it isn't necessarily an art site. I also post on ArtStation but I only mostly put up proper fully finished artworks on there.
Pixiv I plan to hopefully be more active on, I love the website's layout and the fact you can compile multiple images together.
I don't know, I'll think on it more, but I might be moving back to DA if I can't find evidence of DA still supporting tracing / plagiarism.
