This comes from Warren Ellis, in the latest issue of his newsletter Orbital Operations, a couple of suggestions for privatizing your online persona in the coming years.
If you are a fan of Ellis' work and you aren't a subscriber to his newsletter, give it a chance.If you have access to a Windows machine, there's an excellent Twitter archive eraser called Twitter Archive Eraser, haha. All you have to do is request your archive from Twitter, install Eraser and feed your archive to the machine. I mean, if you don't want to delete your Twitter account entirely, which I totally understand, but.(You may want to do something with your LinkedIn account for similar reasons.)Also, iMessage and WhatsApp are okay, but get Signal. If you're going to organise, try to form IRL spaces and try not to use Facebook right now.Keep an eye on Safecast - as they build out their systems, their open environmental data may prove very useful in the coming years.You may want to consider private newsletters - Tinyletter is a very good free option if you intend to speak to less than a few thousand people - and, despite being Facebook-owned, a private Instagram account may be better for you than a public one right now.To the fine human beings whose politics lean to the right - do not assume these are suggestions purely for the weeping lefties, or that I believe they only apply now that the UK and US are under far-right governments. They applied before. I used many of them before.
And remember, having a measure of privacy is always a good thing, no matter what sort of politics that you hold. The idea that having anonymous accounts means privacy isn't a good idea.
