They put my site https://cocalc.com, which has chatgpt API integration, into this gpt4free. As a result, I had to modify https://cocalc.com to require sign in before providing the ChatGPT functionality to visitors, and I also explicitly updated our terms of service to clarify how our API can be used. I made a pull request https://github.com/xtekky/gpt4free/pull/461 to Gpt4free to have them remove cocalc. They were respectful, with some discussion back and forth, and they merged the PR. I personally don't think that Gpt4free should be taken down, so long as they respect the explicit requests of projects they proxy. They were certainly respectful with cocalc.
