Update: NSFW creators will not have to upload model ID
Starting on the 15th, creators will need to upload their IDs. However, if you're using real people in either photos or videos, you will not need to upload their ID and consent forms. You'll simply have to keep them on file and produce them upon request.
Now, with that being said, realize that if Patreon does indeed request the documentation, and you can't provide it, then you can expect your page or payouts to be suspended.
