I have a 1 year old "local crime watch" Facebook group page with 6k members and growing daily. Hundreds of new members monthly. I am trying to figure out a way I can monetize this niche without people really noticing I am making money from it.(unless I have to be obvious to make the money.. Doesn't matter as long as I am.) They are all legit memebers, very active group. Some post even get 10-100 upvotes Any ideas? Anything helps. Thanks.
