Other places to post stuff that aren’t necessarily Tumblr: Anti-genAI edition.
Has anti-genAI policies baked into their terms. They also have Glaze built into their submissions system should you choose to use it.
Haven’t used it much, personally. I’m not going to comment on their fundraising or my outlook on their future or any of that stuff because it’s all been discussed to death like five times over and more by now.
The important part here, is that they prohibit the posting and promotion of works using generative AI.
That said, I’m not saying “go here” or “don’t go here”. I’m not telling you to leave Tumblr entirely. It’s up to you to read these places’ terms in their entirety and decide what to do for yourself. But I know it sucks to feel like you have nowhere to go because you’re being pushed out by the tech companies you rely on, so I hope this helps.
