Mastodonで自分のaccount_idが1ならこんな感じなのかしら
SELECT format('@%s',accounts.username),follows.created_at
FROM follows
JOIN accounts ON accounts.id = account_id
WHERE follows.target_account_id = 1
AND follows.uri LIKE 'https://misskey.io/%'
AND follows.created_at > '2021-04-15'
ORDER BY follows.created_at;
この時刻以降に登録されたアカウントは既に再登録されてると思っていいのかねえ…
