The contacts are broken. I tried my best to have my character kidnapped, but the requests stopped after the second one with every contact, and none of them trigger the kidnapping, it's just reveal information followed by sex.

it's not broken, there are no more requests for them to send after the sex request. i'll add more options in upcoming updates, it's still not completed (as mentioned in the post).
as for getting kidnapped, the chances are slim. only specific types of characters can kidnap you, those that send a sex request before revealing their identity. i might need to adjust it so you encounter those kinda characters more often.
