Mastodon.cloud Abandoned: Security Flaws and Spam Sprawl Force Migration

If you or someone you know has an account on mastodon.cloud, I would highly recommend migrating to a new server. Lots of instances are in the process of completely blocking mastodon.cloud which will sever all connections for people on mastodon.cloud. Mastodon.cloud is effectively abandoned, running very old and out of date software with minimal moderation resulting in a good deal of moderation work for those of us running other instances. I am posting this in hopes that some people on mastodon.cloud see it and decide to take action.

RE: https://fosstodon.org/@fosstodon/116426844488528606 There are comments asking us to elaborate so here are some more specific reasons why we will be defederating. Firstly, mastodon.cloud’s admins have been unresponsive to us regarding large volumes of spam accounts and other coc-violating content registering to their server. Their admin and moderation team are seemingly no longer active. With the server still in open registration, this allows more bad actors to create accounts without moderation and affect the experience of federated servers.

Secondly, their Mastodon software version has not been updated for an extended period of time and has known security vulnerabilities. We do not want to risk any exploits with those vulnerabilities that may affect our users. An instance that is unmoderated and insecure poses a risk to other servers it federates with. The Fosstodon team did not take this decision lightly, and arrived here after months of observing these issues.

Again we encourage you to reach out to any accounts you follow on mastodon.cloud and ask them to migrate their accounts to an active server. This is not only to allow them to continue to participate in the fediverse community but also for their own security, as mastodon.cloud is no longer a secure platform.
