wanted to pop in here and mention that i use AbeloHost; it's low-priced offshore hosting with pretty lax content restrictions. here's their list of prohibited content: https://abelohost.com/acceptable-use-policy/
you'd need to contact them to ask if ageplay is prohibited but i don't think it is— they list "underage nudity" as prohibited but i think that refers to, yknow, real-life stuff.
