Well I do know this: next time I expose my children to something, I will NOT be telling ANYONE. I only told 2 people (fellow non-vaxers) that I thought might want to expose their children as well. I will not make that mistake again, next time if someone wants to expose their children, they can come to me when and if my children actually have the illness.
If your town is really as small as you say, people will find out that you have exposed your children, because word gets around, and the other people may talk.
Unless you're doing it through the mail.
In which case you should be aware that mailing "Infectious material" without meeting certain safety criteria is against USPS regulations and may be a violation of the Patriot Act.
