So, now that mastodon.social has made this issue public I can disclose that awoo.space had the same misconfiguration issue. If you exported your data it might've been leaked. I'm not sure how long it's been configured that way but it must've been since before I was the admin.
Awoo.space is a Mastodon instance where members can rely on a team of moderators to help resolve conflict, and limits federation with other instances using a specific access list to minimize abuse.
