Yes! This was the sort of advice that I've been looking for! I've been using a bullet-point ad for 19 to advertise this place, but maybe the algorithm in their filter has changed, possibly in response to AI slop. I'll rewrite it with sentences and see where I get.
Thank you, ex-flagger! It's nice—and rare—when I bump into someone in these forums that actually has something helpful and kind to say.
