Mastodon is currently one of the leading services in the so called Fediverse as a federated online social network, so its inner workings are of special interest to understand and for attackers to potentially abuse.

The general architecture of the Fediverse to understand the design possibility for such attacks is also taken into account as well as ethical considerations to conduct research on a real social media network.
It covers a part of current research as one example for the trust built into the design of most (ActivityPub) Fediverse platforms.
