The courts have a different standard though, and so it is much easier to get them to see. DMCA also is submitted under penalty of perjury, so if there is no infringement, then the courts can take criminal action against the accuser.
I'm not clear on exactly what is being claimed so I don't know how real it is in this case.
No, it's not, except for the claim to copyright ownership of the allegedly infringed work. Particularly, the claim of infringement is not made under penalty of perjury (which makes some sense, as it is a legal and not a factual claim, but you don't have to allege the factual basis for the claim of infringement under penalty of perjury, either.)
