The solution to your problem requires practical advice, not as much legal advice. I could tell you about possible lawsuit claims you might be able to make, but the reality is that you could not collect a judgment against these other public housing renters without money even if you could get a judgment, because there are probably no attorneys who would take a case with such a small chance of collecting on the judgment if they get one. What they are doing is wrong, but on a practical level it does not appear you have a legal solution.
Perhaps as soon as you finish school you can move away and leave those jerks behind.
Good luck to you.

Talk to the management of your building. There is a complaint process available to you. This is a violation of the applicable rules for tenants and the management should investigate and deal with it appropriately, even if they have to resort to logging tenants who use the computer. Make a good fuss and also reach out the local legal aid organization that is most visible in interacting with your particular housing agency.
Make a formal written complaint to the agency that administers your housing. They can force the management of your building to take an appropriate enforcement posture here.
My responses to questions on Avvo are never intended as legal advice and must not be relied upon as legal advice. I give legal advice only in the course of an attorney-client relationship. Exchange of information through Avvo's Questions forum does not establish an attorney-client relationship with me. That relationship is established only by individual consultation and execution of a written agreement for legal services.
This is morally and ethically wrong, and may constitute some level of harassment that your landlord should put a stop to. It may even be enough for you to seek out a restraining order.
However, I don't think it is illegal, especially since you posed for the photos and allowed them to be included in some website. They are now part of the public domain.
