yep, Primal has censoring filters, you miss a lot of content using Primal, their algorithm seems to be trying to stop 'spam' thus the filtering may shadow ban people due to their post (whatever the algorithm builders set to he banned ala Twitter)

If you want to experience an uncensored Nostr as it was intended, I suggest you stay away from clients that censor, the blocking and muting and reporting should be done by the user not the client's masters.... FFS!
