A lot of whining here about how this is an imperfect response to the issue of children being exploited on Discord / using the platform to engage with inappropriate content.
Until someone offers up something better, I take these types of initiatives from social media platforms as huge wins. Ignoring the problem will not make it better. We've been ignoring it for about 20 years now, and it's only gotten worse.
The solution is parents! Stop making your bad parenting my problem!
I wish I could simply show Discord my adult genitals as evidence of my adult-hood.
The sharing of my ID with a known incompetent company & business seems like a risk they're foisting upon me.
Be responsible for your spawn and don't be a weenie about asserting boundaries for them.
The thing stopping kids from getting "exploited on Discord" ought to be the same thing that stops them from stabbing each other with pencils. Raise your kids better, and stop expecting everyone else to tolerate your failure to do so.
