walking mirage

every time I see "cw: porn" I age 6 months. I am now 945 years old & getting no younger

cw: suggestive, holding hands, friendship

agreed. fedi/mastodon/etc also has this same problem, but amplified because people use CWs both for, like, body horror, death and dismemberment, y'know, "this is actually traumatizing to look at for many people" and "CW: car door", "CW: food", "CW: talking about computer" and I rarely see one for dogs, a very common phobia (one I don't have, but I know people who do)
so I get alarm fatigue and just click-through CWs blindly, and I've been smacked in the face by this already.

imo content warnings should operate on the tags framework to help people gravitate towards phrasings held in common, potentially localizable, and most importantly filterable such that you could do something like this by topic (and the reverse: do not show me posts with these content warnings at all)
of course for automated filtering to be functional requires a better shared understanding of what warrants a content warning, as demonstrated by even tagging being fairly patchy. "how to tag things" and "how to content warn things" are cultural problems not technical ones and then people crossing platform boundaries bring their own assumptions of how these things work.

i need this on every platform that uses content warnings honestly

I think ideally, you would have a system where the user can have multiple CW categories (with specific text-input CWs within those categories) applied to their post, categories could be stuff like "Extreme kink", "Violence/Gore", "Phobias", etc

And then if you don't have any issues with a specific category (e.g. you do not have any phobias) you could set it to automatically ignore all CWs in that category.
