Yes, that's the same dataset. This website has some additional tools coming so artists can flag and opt out, or upload to opt in, and we'll get those to the laion team to add or remove from the 5B (and future) datasets.
What's your approach to establishing authorship? I'm sure some trolls will try to claim things they didn't actually make and get them removed (and vice versa).
Our initial approach will be to validate the artists manually, and trust them to only flag or upload their own works. If we hit a scale where that starts to become an issue, we have plenty of ideas for mitigating this, but we're not optimizing for that problem yet.
You have no way to stop people from uploading content that isn't theirs. Worse, you have no way to stop your program from stealing uploaded intellectual property.
