I think the best thing to do if someone threatens is to call the Police or 911 and then that person can be taken in for a 72 hr hold. I mean, if someone verbalizes it, you don't know if they are serious or not. If they are, they will get proper help. If not, they will then not be saying that again knowing your are going to call for immediate help. I mean that is what I think would be wise to do in one's personal life. For online stuff, I would assume that something would be reported to the Board Administrators and support? Not sure
