I think they were asking if you were a bot because your account has been set up as one: your profile on mstdn says 'automated', and if you do curl --header 'accept: application/activity+json' --location <a href="https://mstdn.social/users/internetisscary" rel="nofollow ugc" target="_blank">https://mstdn.social/users/internetisscary</a> | jq . then it says your ActivityPub 'type' field is 'Service' rather than 'Person'.
