I'm definitely not going to ID myself to go on social media. Then I'll just quit (in fact I've quit most social media already anyway due to the enshittification). Even a parameter linked to my real ID is not acceptable to me. And also, after social media, I'm sure other sites will start demanding more checks as well. It's a slippery slope.

Luckily I don't live in Australia but I find this a troubling development. Anonymity on the internet is necessary. Because it is much more permanent than the real world. Every little misstep can be dissected decades later.
