The situation with Artstation (and other image publishing sites) is tiresome and irritating. I like to share with people what I drew, I don't want to hide it on hidden pages secured with five passwords. Yes, people had stolen my pictures before, but I could live with that. Bots sucking my and your creations into a large base so that the big corporation can get even more by training image generators on all this. Portfolio sites that sell/use access to beautifully described and sorted work.
At the moment, there is no sensible place on the web where you could publish a portfolio or create a community.
I don't know what to do in this situation. I'll wait for now.
