Looking for Mastodon users progress, scanned 366 of 366 users you follow on Twitter. Discovered 0 Twitter users on Mastodon who have previously linked their Twitter and Mastodon accounts by logging into Twitodon.
Was a bit surprised that it found 5 matches (out of 1659 people I'm following). A bit inconvenient that I can't just see these matches though, but have to download a CSV file first.
