@fediversecounter@mastodon.social
An automated account that posts information about instance, user and post counts for the Fediverse. It uses scripts that walk a list of instances querying their statistics APIs to obtain this information. It also builds web pages that contains some additional information about each instance, such as max message size in case 500 characters is just not enough. Its list of instances is not claimed to be complete, nor the statistics accurate since it relies on instances to self report accurately.
