Since you're in different FCs now, see if your FC leader will close the FC house to non-members. Then you'd have at least one place where you couldn't be bothered. Outside of that, take friends with you and have them report your stalker, too. And try to ask strangers, too. You don't have to be the one being harassed to report someone for harassment as long as you witness it. So people nearby seeing you being stalked can report as well. The more complaints filed against that person, hopefully the faster the issue will be taken care of.
