Sure. And I'm sure that their users will take kindly to being banned with prejudice and without recourse. By adopting this policy they are committing to policing it and acting as judges. And at some point someone will be banned that shouldn't have and it will go on social media and so on and so forth.

They'll also have a fun time drawing the line. What if someone uses agents to generate boilerplate like tests? Are a few files out of hundreds enough for a ban? If not, are they going to force users to write the code manually? How are they going to verify that?

It's a big can of worms.
