If you want to follow specific organizations, unfortunately, there aren’t as many on Mastodon as on other social media platforms. Some are accessible through Threads.net federation, like @theonion@threads.net, through the Bluesky bridge, or via other non-Mastodon federated communities (e.g., Flipboard.com) if that’s something you’re interested in.

However, some communities do wall themselves off from bots and bad actors. For example, the most popular Mastodon instance (mastodon.social) blocks the second-largest instance (pawoo.net). Other instances, like mastodon.art, defederate from AI art supporting instances, while others like hachyderm.io has defederated from Threads.net. Additionally, some Mastodon communities, like Truth Social, are entirely isolated and defederate from everyone else.

So, if you want access to the widest range of communities, you may need to join more than one instance.
