fwiw I just DMed a link to this comment as my age verification. I don't think Lodion is being too strict about it. Just DM a story about some cultural touchstone from your childhood and you'll probably be fine. No real need to go elsewhere.

If you do decide to move elsewhere though, Piefed sounds pretty good these days. I'd probably avoid quokk.au (even though it would actually be my first choice otherwise). Lemmy, Piefed, and Mbin are pretty much the entirety of the threadiverse as far as I'm aware, though I'm not sure how feature rich Mbin is and I'd probably avoid it on that ground.
