I've seen multiple requests for nsfw lemmy communities like reddit has. I live in Germany, and I think you are required to verify that the users that see porn content are above the age of 18. Does Lemmy has or plan to have a feature for that?
Maybe this should be an issue on github?
I can verify myself using my Id card and a terminal or via NFC. The app used is the middleware between software or website requesting verification and my ID. No data leaves my ID in direction to the software or website. The middleware just gives a thumbs up to the verification request.
The thing is, the "software" actually is open source, so you can tell how data is requested from your smart ID. The german government ID has an explicit function for age verification that does not provide any personal information. https://github.com/Governikus/AusweisApp2
However it is probably hard and costly to get certified to use any of those functions as a service provider.
The thing is, that it is only required if the company is located in Germany. Thats why pornhub, a company run by Germans (afaik) does not have to do it... It was in the news multiple times, when the government tried to remove that condition so all porn sites accessed from Germany have to verify the age of the German visitors.
