Exceptionally frustrating situation...

Fleury29, as this is a long-term pattern, is it possible you are somehow broadcasting a social vulnerability the exploiters and cruel among the population home in on?

You have tried to tell these people to stop. That they don't is an indication of their pathology.

Moving is an option. You may not have to move far, just far enough to get a fresh start.

You are describing a truly disheartening situation on which depression can feed.
