Is is a rule you cant have the same plot(or base it one the same books) in multiple rooms? I have been being harased about having to remove my room because theres another room based on the same book

I created a warriors rp, because there was alot of out-of-rp drama in the other one(Warriorcatsssssrp) and I was truthfully getting tired. But all day I have been having people say I have to take it down. Why though? I dont renember a rule saying two rooms cant be based on the same thing(and if there is a rule like that, its pretty stupid truthfully).
