Something I haven't seen anyone talk about with #Discord enabling #AgeVerification by default and globally is that they're not just blocking you from NSFW content when they make your account a "teen" account. They're also turning on message scanning and nagging popups every time a rando sends you a friend or DM request.
I'm sure the latter would be seen as a tolerable addition the first few times it happens, but not the first few dozen.
The former means that Every. Single. Message. You. Ever. Send. is going to be processed by Discord directly. Never mind the fact that I don't think you can comply with #GDPR while doing that, the fact that they're doing it at all means they can choose to filter out any other possible thing. Like, say, if a government decides you need to be an adult to access sex education material or depictions of even platonic homosexual relationships. Maybe that same government then decides to mandate content about certain political topics, like when TikTok straight up banned users from typing "epstein" in a message.
You can't turn that off now without submitting either video of your face or a photo of your ID to a company that had a breach where MILLIONS of IDs were compromised less than six months ago.
