I think there needs to be individual degree of control beyond just the labels; especially for individual/small servers where owners might feel more individually liable.

For example, even within the NSFW space, there’s a wide varying degree of acceptable-ness depending where you are in the world and what your personal feelings are. A server owner in a more repressive parts of the world may put themselves in harms way if any LGBTQ+ (and apologies in advance, as I know I’m missing several letters and number, but I don’t remember the sequence order) content. Further extreme of the spectrum, “legal” age of drawn characters is another huge legality concern.

Simply having labels and depending on community moderator to label correctly (or even allowing server operators to try to override locally) seem like a only a very basic starting point, individual override is a must to prevent content that may get operators into trouble from even being shown in the first place.
