+  I finally deleted all my Twitter accounts, notably @theory. If you see that
+  username, it's not me.
+tags: [Twitter, Personal]
+type: post
+---
+
+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].
