You don't have to use social media. You can just not do it. It's not required.
I understand this breaks a lot of societal interactions. That's the point. The internet is punk rock, social media is top 40's with heavy advertising. It's much easier to just tune into the feed that someone else made for you.
Running your own shit on the internet, having your own domain name, participating in contributing instead of just consuming... takes effort and money. It use to be difficult to understand how to run your own shit but those days are gone. Search for how to do it, use LLM's, take a leap of faith, make mistakes, learn one of the hundred ways to self publish, have an ugly website, find your voice in writing, and realize your website is now out in the aether. It just exists, floating in space time, waiting for a TCP/IP 3-way handshake. As it should be.
You can post the same things you do on social media. Or not. You can say words like suicide, gun, kill, anorexia, or other words that forced Orwellian algospeak into existence. Fuck self censorship.
If you don't have money, look up free ways to do this. Get creative, be subversive.
If you have money, do it yourself and spend a little cash. Get creative, be subversive.
Another internet is possible, another internet is here and has been here since the early days. Consider this your official invitation to join.
