I quit Twitter in November 2022, when it became clear that Phony Stark would take control of the company. No regrets; I’ve been active on Mastodon since then, via Ivory, where I’ve enjoyed the Twitter ca. 2010 vibe.

But I hadn’t deleted my Tweets or my accounts until this week. The change was finally triggered by the latest announcement:

On Friday, X will adopt a new terms of service policy that for the first time explicitly says all users agree to let their posts be used to train artificial intelligence, like the company’s generative AI service, Grok. Currently, X users can go to the site’s settings and opt out.

I have no interest in feeding Grok or any other large language model. So this week I deleted all my tweets and then my accounts. I tried to transfer my personal username to a new, empty account, but in the second between changing it and switching to another tab to take it, it was somehow acquired by an account created in 2011 with no posts. Not sure how that worked. Pretty scummy.

So, just to be clear, anyone using these usernames on Twitter are not me anymore:

• @theory
• @lunar_theory
• @DesignScene
• @pgxn

See you on Mastodon — or perhaps Bluesky.
