Agreed. 

 Just curious, why was Primal engaged in shadow banning or was it something else? 

 I do not agree. it is completely up to the user and client to use their discretion. don't like built in filtering? use one of the other 100 clients or apps.

There are many relays that only have some content, ie: christian, god, religious notes. should that also not be allowed? isn't that the same thing?
