Ara,

Im in a situation somewhat similar, but mine involves busy body, old retired neighbors.

your landlord has an obligation to act on your behalf. have her put everything in writing to the landlord and demand a stop to the situation. also, consult the police and get them on your side. video tape EVERYTHING. most likely, they will retaliate, usually on your personal property (cars, etc). it can and will get ugly whenever people try to socially correct others.
