Being evicted for non payment of rent went to court won, landlord is suing me again for the same thing?

I Have been living in my apartment for over 18 years, landlord came and offered me money to move, I decline, went to court won my case the landlord is still trying to evict me, is this legal, I read that the owners can sue you 12 times a year, I don’t have money for an attorney, I went pro per, I can not keep paying filing fees, the owners are harrassing me to move, is this a legal ? not only myself but also my neighbor who also been living here for about 25 years, she also won her eviction case and now they are also taking here back to court.
