Nah, Twitter is still absolutely rotten with toxicity. The Great Xodus happened due to the rapid chuddification of Twitter under its new management: it was over politics, not toxicity. As such they brought the toxicity with them like a plague.

Bluesky has this nice feature where you can mute lists, so someone made a MAGA list (https://bsky.app/profile/skywatch.blue/lists/3l53cjwlt4o2s), and yet I was still seeing MAGA stuff on my feed because all the Twitter refugees were screenshotting Twitter nonsense and laundering it into my feed. Utterly ridiculous.
