There's no reason both the landlord and the tenant can't both be in the wrong.
I would try to sever any relationship with the author of this site as well. He's toxic. Granted, his landlord is not an angel either.
There's thousands of shitty landlords in NY, try something more meaningful this just comes off as vanity.
edit: and by do something more meaningful i meant, activism to fight against all the poor landlords or something, rather than just this ego project.
