I've heard it from a few people and been on the receiving end myself; you criticise or even offer some constructive criticism on how to make something better (as I did), and you get banned, not just from Discord, but Patreon too. From this, DPC would appear to be very single-minded and not interested in what their fans/supporters didn't/don't like. They don't have to like it or even do anything with the suggestions and criticism they receive, but they should at least allow it. Sometimes it can be good to get the perspective of others as it may change your own viewpoint, but DPC doesn't seem to be receptive to that at all.
