I don't like them much too. Too often they are too few responses and just sage the best threads.

I would postulate for a new board where low and medium quality posts are prohibited because I would want to make original threads with significantly more effort than just dropping one picture and no text as I used to. But the thought of speed at which heyuri goes these days is horrifying when you put a lot of effort to get 1 reply and drop from page 0 in half the day forever.

I would post cooking, crafts, tutorials, heyuri exclusive sanpo pictures, local things i dig up from the past and relics, local library reviews, cool link and magnet collections and they would be a good place for OC in general I think.

Maybe the rules could be:
1. For the thing to be made by you entirely including own OC, own ideas, own photos and so on with references and reposts allowed unless they oversaturate the thread
2. OC to be more than low quality (low effort)
3. Replies to bring substance as well, whether supportive or dissatisfied to prevent oversaturation of the thread with one line replies that are not even genuine

Not everyone would like the threads or plain be angry because the board would possibly look like an elitist curated garden of select few attention seekers but that environment encourages quality

Quality takes time and in a slow and clean board you feel like you have an eternity to finish something and share it
Originality makes the threads more risky because the idea has not been tried before, but if nobody innovates then there can be no cool things discovered, fear of shaming (and reckless shaming) and laziness are the vices
