I have an inmate sending harassing messages through Facebook messenger. Do inmates get privileges to get online.? If not, what do I do to report him?

Inmates are not permitted access to the internet. However, there are some services where an inmate can pay someone on the outside to do their posts for them. BUT, if he is harassing you, you can call the facility and ask to speak with the warden's secretary. Give them the details and request a call back or you are going to the local police. This could become a serious issue so be careful
