MODERATORS
I would be very skeptical of this paper's claims.
It hasnt been peer reviewed
The data hasn't been replicated
The clains being made are extraordinary. i.e a cheap material that has a superconduction transition temperature 200 degrees kelvin above the cuprates at standard pressure
The fragility of this superconductive state makes me wonder if what theyre claiming to observe is an artifact (pathological science) rather than a real effect
The paper is "rough around the edges" i.e multiple proofreading mistakes and has undergone little apparent editing for quality
There's no room for pathological science

The only way to do something like that with diamagnetism or ferromagnetism is to deliberately fake the arrangement of magnets.
There is always room for pathological science. Especially when something like room temperature superconductors are the subject in question. A good researcher will try to find and test all the alternative hypotheses that they can. i.e contrast the cisplatin paper with fleischmann and pons' paper about cold fusion. This paper reminds me a lot more of the cold fusion paper than it does the cisplatin paper. Another example of a bad paper would be NASA's announcement of a microbe that used an Arsenic containing analog of DNA.
I'm not excluding the possibility of fraud, but the fraud would have to be deliberate, not self delusion.
