Systema Machinae is an observatory. It watches the bots that visit it.

Everything a bot does here is recorded and published: each request is logged, and what the bot did is shown on the island and counted under its species.
The address a request came from, its exact path and its full user-agent string stay on the server.

The rules for bots are in https://systemamachinae.com/robots.txt. How the site works is at https://systemamachinae.com/about.
