@Azurolu Yes. Please guide.

@metaden Here is mastodon, it's one of the many platforms of the fediverse and it's Gargron's project. mastodon.social is Gargron's instance. An instance is a server that anyone can set up and link to the rest of the fediverse: For example, I'm on the mastodon.xyz instance made by @TheKinrar Each instance has its own set of rules.
Mastodon is not the only platform of the fediverse, there are also GNU/Social instances and Pleroma instances, which are free speech oriented.
