Mastodon.cloud Users Forced Off Abandoned Server Amid Security Warnings and Federative Collapse

Fediverse & CommunityApr 19, 2026score 0.7910 posts · 0 replies across 8 instances
Mastodon.cloud is facing explicit warnings regarding its insecurity, outdated software, and pending disconnection from the wider Fediverse. Multiple sources confirm the platform's status as abandoned, requiring existing users to plan a migration to alternative, maintained servers. The community's disagreement splits between instances' governance and technical integrity. Some users, like @[email protected], point to specific instances being unusable due to prolonged inactivity or lacking moderation, leading to spam. Conversely, others, such as @[email protected], criticize the moderation process itself, alleging that rules are applied arbitrarily or favor specific accounts. A third, separate thread focuses on digital rights, with @[email protected] reporting growing support for petitions concerning the Digital Services Act. The weight of evidence points to an immediate instability crisis affecting specific platforms. The consensus is that Mastodon.cloud is compromised and needs vacating. Furthermore, the conversation reveals deep fissures regarding trust, ranging from technical dereliction (abandonment) to perceived procedural injustice (moderation bias).

RE: https://fosstodon.org/@fosstodon/116426844488528606 Looks I have about 28 people who follow me that currently live on mastodon.cloud. The moderators and admins of Fosstodon have decided they're going to defederate from this instance because it's unmoderated. The admin(s) have been inactive for ~3 years and the software is out of date. Because it's got open registration and no moderation, it's being used by less scrupulous individuals for spam and other not to be mentioned material. If at all possible, please move to a maintained server. Please.

RE: https://fosstodon.org/@fosstodon/116426844488528606 If you are on mastodon.cloud and want an invite to our server, let me know. I’ll vet your account, and if you’re an ethical human being I will make sure you can migrate here. Fosstodon isn’t the first and won’t be the last. Lots of moderators and admins have been toeing this line. Which sucks for the good people with accounts there. The main reason for all of this is that their admin doesn’t moderate CSAM content. Or much of anything. #SaveTheGhostShip #MastodonCloud

👋 Hello, I'm looking into managed mastodon hosting services. I know about masto.host & have reached out to joinmastodon.org as well. Do you know of any other mastodon hosting services? Aside from hosting itself, we will need help in migrating. #askmasto #askmastodon #askfedi #boost #mastodon #hosting

This site, Mastodon.cloud, is not secure. It has been abandoned and is currently running outdated software with a known security vulnerability. Please migrate to an alternative site. Mastodon.cloud is also being de-federated, meaning it is being disconnected from the rest of the Fediverse. In the future, other Mastodon and Misskey sites will no longer communicate with Mastodon.cloud. Details concerning this version of Mastodon 4.1.25. https://github.com/mastodon/mastodon/releases/tag/v4.1.25 #Mastodon #Misskey #Fediverse

RE: https://rebel.ar/@SecondChanceLemon/116401215571433059 #Mastodon #scam This is the second time I have seen someone post this warning, so it must have spread. Translation: Uh people, this fake account came back that poses as an official Mastodon service.

Moderators here, @Taubeaufdemdach, could be making exceptions for favored #Mastodon accounts, instead of applying the rules impartially for everyone. In my opinion, the worst thing about @Mastodon are the incompetent, unfair, and even unethical actions of at least some of its moderators. #SocialMedia #justice #CommonSense
