@anna I already try to encourage people to migrate off instances that are very big, regardless of who runs them, because consolidation not healthy for the internet. That said it is difficult to actually block dot-cloud in my case, but I will keep a closer watch on them.
They already operate a couple other instances, and claim to be an "official Platinum Sponsor of Mastodon". So what does that mean? Is that an indicator that Kibousoft is benign or a concern about their influence on Mastodon?
