I'm seeing a constant stream of POST requests, every few seconds, to the Activiypub URI's on my website from different IPs from Hetzner but all having user agent "Mastodon/4.5.0-rc.3+pr-36715-b18ea4a (http.rb/5.3.1; +https://mastodon.social/)"
Could this be legit, or are we dealing with bots who falsely claim to be mastodon.social?
