Fedistats is a project that uses data from the fediverse (mainly mastodon right now) to find new trends and interesting content on the Internet.
We're using the federated timeline endpoint that is provided by the mastodon API.
We're aware that the mastodon community is quite sensible about privacy, and protecting its members and we agree. Therefore we will only provide aggregated data and never data on an individual level. Still, users of mastodon should be aware that most of the data is public by default, which means it can be retrieved without any form of access control, and the data is already actively crawled, for example, by Google (just search for "mastodon" and your username).
Also note that this is a prototype under active development, so the numbers provided may not always be right. :)
