The reason we got into joinmastodon.org is because our timeline reviewed and any reports made on the system was reviewed. They couldnt find a single incident of sexism or racism or any other sort of hate speech that wasnt promptly addressed by a moderator...
If you'd like to claim that we "clearly don't" follow the server covenant (which is in fact our rules explicitly do follow) then can you please point us to a single incident where the covenant was violated.
As Rob said, your welcome to come review our timeline and try to find such an incident.
