I love this kind of community in theory, because I love learning about how things work, but I don’t love the posts asking for creature identification. Those are less how things work and more “I need an expert on this geologic region’s fauna” so they seem like completely different topics to me.
I don’t want to see spiders in my feed, but I’m happy to see curious objects. If I block the community due to the spiders, I miss out on the curious objects.
The community averages less than 1 post per day; it’s not like it’s being overrun with animal identification requests, and there’s certainly not enough to warrant a separate community. Maybe just ask for spoiler tags on spiders instead?
