For the longest time, posts with a content warning that we make, particularly those for Splatfests were not visible but now they seem to be?

I'm just wondering when this started happening since I've only noticed this just now and it's a bit of a concern for me. I'm not sure what clients are used for Lemmy but I'm concerned that the clients may show contents of the message despite showing an NSFW tag on Lemmy (obviously we're not posting any porn). The whole purpose behind us using content warnings for stuff like this is to not spoil people.
