The source doesn't actually say whether submissions not advancing "SPSP's goal of promoting equity, inclusion and anti-racism" would be accepted though.
They would pass the reviewing process where they would receive the lowest score on the "3-point rating scale".
It would also mean by negation that the submission did not employ "diverse research participants", "diverse research methods (e.g., methodology that promotes equity)", or "diverse members of the research team", which basically would be viewed as a self-indictment in our political climate. Nobody with an interest to succeed would willingly arrive at this conclusion, they would view it as necessary to avoid it (like by making up reasons as to why the submission advances anti-racism).
In other words, the requirement to include the statement is a way of enforcing the stated goals and policing the researchers' conformity.
I'm not sure that this is really a problem. The sample of "57 college students that we forced to participate" is a bane of psychology research even if we ignore the racism angle. So what's wrong with writing a paragraph about how you took pains to get a representative sample?
