Update: The men may now be harassing me "behind my back" but it's too early to tell. If this behavior continues on I will know for sure. I spoke to the landlord today about this and they said that if I feel threatened to call the police. I am now at the point where I will the next time. They also said the men will in fact be gone at any time now but couldn't give details. That was a relief to hear again.

Apparently where I live harassment is actually a serious crime. It appears that it can be any speech or behavior that serves no purpose other than to intimidate, cause fear or emotional distress. I never knew this. I never had to. I'll update when anything noteworthy happens.
