There’s a constant influx of new communities with softcore sexualized characters, especially anime girls, that I could do without.
I don’t mind anime and manga in general, so I would rather not block the instances that specialize in it, but blocking softcore communities one by one seems be a never ending task.
I also think it may be off-putting for new members.
I’m in the same position as you. I haven’t found a good solution. I just keep blocking each individual community when I come across it in the feed.
