Whoops I edited as you were posting. For convenience here's what I added:
"The straight solution of disallowing sharing of zodiac signs would probably have a lot of backlash. It's fun to share our signs and compare ourselves to the supposedly common traits of our animal. And it's not instantly incriminating. But in my opinion it's incriminating enough for a LOT of CS posters that I really feel that it is an issue"
Security usually comes at the price of stuff like politeness, convenience, and fun (because those are exactly what malicious people target lol). I'm used to this by now and have embraced it, so I wouldn't mind if we just disallowed zodiac talk entirely. But it's always been a PITA for security people to get the general public to accept security measures, and I bet that'll be the same here.
A lot of the problem is that we're talking about CS users, not the entire world. If you're on CS I bet you're in a developed country and have followed traditional education age rules or whatever they're called. So with that restriction, stuff like grade level and zodiac sign are just... too much, more than they already are. I'm already seeing in my mind people pulling counterexamples from the people that I doubt would be on CS in the first place (e.g. adults in underdeveloped countries who are finally getting access to ed and tech) to argue that they're not that bad when they actually are because we are on CS
Edit: or maybe I'm just being really cynical lol
