First, I'm not going to give any social media my ID.
If someone intends to expose your ID to hackers due to Twitter's poor security performance, this presents a perfect occasion for them.
I don't know why these social media companies are so fixated on asking for personal information. And I'm sure this is just the beginning of Elon's grand plan.
Perhaps it's time to abandon Twitter and move to other fediverse or decentralised platforms? I would love to see a mass migration.
In both cases though, there is a legal requirement to prove that you're above legal age to buy/consume alcohol. However, there's is no legal requirement to provide such information to a social media platform.
“Yet”
Sure, but if they're not really private information, then what is the concern? It seems to function similarly to an email address, kinda? Something I'd really rather not be shown to the public but also something I'm giving out to the public all the time.
Although it's relatively not so private, I'd still rather not be giving it away to social media. Unlike an email, your ID, full name and DOB is enough for scammers to use your name for shady stuff, at least in my country.
It got to the point here that scammers get older/retired people IDs to open bank account and get loans, leaving these people with debt + the whole legal process.
