I think it comes before that - the first pieces of data they are scraping. I don't buy that the problem is that they can and will infer your age/gender/etc. based on that.
I'm not sure but I'd also be interested to know why information that used to be printed in any phone book for the world to see is suddenly the most private information to hold dear.
I might have my hottest take of all: Anonymity is bad for the web and (ironically) makes us less safe. It creates a power imbalance. I'm only "anon" here because others are. If nobody was anon (somehow) we could know our attackers, trolls, and harassers and take action.
Anonymity on the internet protects a lot of us from state actors, governments, and fringe extremist groups. We're already losing that anonymity with many state laws (submitting IDs to view adult content is one of those). Imagine if the President had a list of every person worldwide who said anything bad about him. Name, number, gender, age, address, list of friends on every network, etc.
Having to deal with trolls and harassers that can be blocked or removed from the platform for gross violations is a much better option than everyone in the world being able to find out who I am, who my family is, who my friends are, etc.
All the bad actors will do is steal someone else's credentials. Just like they do now. You still won't figure out who they are. They'll set up networks of fake names, fake friends, fake businesses, fake pages, fake comments, fake posts. They're not going to just roll over and start doing shady shit in their own names.
Looking through Discord's ToS and Privacy Policy, gender isn't mentioned once. And age is mentioned once in the Privacy Policy in regards to account creation.
This practice circumvents the law by gathering this information without the user's express permission.
To me, this strikes me as someone walking in the park with a stroller getting indignant about someone assuming they might be a parent.
You hear that, HN? Not providing an option to delete our comments is against the law (in California and probably in EU as well). No, anonymizing the comment doesn't count.
It would be nice if HN, or literally anyone, offered that option.
