In this post. Well, mostly nevermind. Mostly. As the way things are going now, you really can get a domain taken away from you, if you are known to have Very Bad Ideas™ and incite violence. Most of you that read this won’t need to worry about that since my readership aren’t of that stock (that I know of), but folks who have the ear of powerful people can be very touchy these days, and it’s getting to be that expressing the Very Bad Ideas™ will be synonymous with inciting violence. You’re far less likely to be deplatformed if you incite violence but think Very Approved Ideas™. Humans are excellent at rationalizing a special plead deal with the unwavering gods of logic when it comes to the behavior of their in-group.
Some quick ideas. At the very least, if you’re neck-deep in Google’s services, schedule backups every now and then with Google Takeout, and store the archives locally, or on Dropbox or your hosting (not on Google Drive, obviously). Register a non-Google email address, like at Protonmail, and maybe one that doesn’t identify you personally. Use Firefox or a Gecko-based browser, or Tor, for browsing. Use Startpage or DuckDuckGo for searches. Buy another domain and, like your email address, keep it non-identifiable back to you.
