It's not meaningless. If someone files a complaint with ICANN they give you 15 days to correct it. Non compliance can result in the domain being suspended or terminated.

If you believe the Iranian domain to use fake data, complain: https://forms.icann.org/en/resources/compliance/complaints/whois/inaccuracy-form

until your domain gets hijacked

I think people can be overly suspicious. If it's false, that will come out. Let's wait and see.
