In the crypto community there is a common and very important saying:
Not your keys, not your crypto.
Meaning if you don’t manage the private keys to your wallet, someone else is. And whoever that someone else is, they actually own your crypto. A lot of people are learning this lesson again with the fraud at FTX.
I think we need another saying for social media.
Not your domain, not your words.
If your writing is on some website where you don’t control the domain in the URL, then it isn’t your writing. Whoever controls that domain name, they can do whatever they wish. This lesson gets confused in hand wringing about censorship and freedom of speech.
If you want your words to be yours, get your own domain name, and put a website on it. There are several services that make this easy for a small fee.
