You're looking for Creative Commons, if you want a real license that's legally enforceable. Creative Commons is weird. Its got similar flaws to those a lot of legacy permissive software licenses have. But it is legally recognized and actionable - its a license with legal magic and not just an interpersonal social contract.

Some of those software licenses look kinda cool. At least software girls are creating derivative work and need to confront these parts of the community. The digital arts community has a very odd relationship to the derivative arts. History stuff, weird, I'd need to write another essay to explain and I don't want to. If anyone's making a unified permissive license with some real clout behind it let me know.

F2U is a shorthand I use on images I have no legal rights over no matter what. Even so, "everything is F2U if you're not a coward" is true they're not going to sue you for 100000000 dollar.

1. A serious cease and desist you need to obey under threat of legal action is the worst outcome. This is a slap on the wrist.
2. Web zones like Giphy and Fandom and Imgur are commuting mass copyright infringement, that's the entire business model. Godawful web zones like Facebook and Reddit and Youtube, too.
3. They can't even sue AI lmao, your safe.
4. Worst outcome is social - getting flamed by 999 teenagers - kinda sucks but j mean just don't be a coward and you'll be ok.
5. Worst outcome is getting banned lol. Why do zoomers care so much about being banned? Its so easy you should get banned more.
