I know it’s ILPT and I usually like reading them but there’s situations where to get the result the person wants they should avoid doing illegal shit. Assuming the goal is to get the roommate out and not get evicted, doing illegal shit could put that at risk. Hell it could actually result in the OP being banned from the apartment while still being on the lease and responsible for rent. I remember reading a case where a guy wanted his girlfriend and her kid out of his house after a breakup and she wouldn’t leave. He decided to get revenge by having friends over constantly to party (alcohol and some drugs). She called the cops and in the end this dude had to spend over 3 months in and out of court before he could move back in and she was forced to move out. During those 3 months she moved a dude in and sold a lot of their stuff. During those 3 months he was also still having to pay his mortgage or risk the consequences.
