I like how on Mastodon the racists, trolls, misogynists, and right wing conspiracy theorists helpfully cluster themselves on servers together. When one hops in your mentions, a simple domain block stops them all with one tap.
@mike Bonus for new folks: The /about pages on Mastodon instances may include a list of "Moderated Servers" (e.g. https://mastodon.social/about) and/or rules + a code of conduct (e.g. https://hci.social/about/more)
hci.social

This Mastodon instance is for the community of human-computer interaction researchers and practitioners. Mastodon is like Twitter but better because it’s open-source, decentralized, and federated. This instance is hosted on Google Cloud Platform servers, paid for by @Princeton HCI, and administered by @YuhanLiu, @nigini, @axz, @andresmh.
