Why does the McAfee WebAdvisor extension swear at "parked domain"?

Question

Search Engine Optimization

What kind of nonsense?
How does McAfee WebAdvisor determine the "parked" level?
What does he mean by "parked"? Maybe there are different ways of parking that I don't know about, or parking a domain is no longer fashionable?

The domain is registered on reg.ru,
NS are registered under cloudflare,
on cloudflare A there is a record from the server ip,
it meets nginx on the server and gives the site.
There are other sites on the server that are no different from this one, and so it doesn’t swear at the rest.

Answer 1

ns not updated everywhere
