No, because it’s not against the law to scan servers on the internet. If you don’t want people to scan listening services, don’t let those services listen publicly on the internet. If you were to log into the server, though, that would violate the CFAA.

I know that current caselaw holds that it's not a violation of the CFAA to portscan in the general case[1]. I'm not asking in the general case; I'm asking specifically in the case where the scans are regular and ongoing, and the scanning party has been explicitly given notice that they are unauthorized.

The courts recently ruled on a similar case[1] and came to the conclusion that it was not a CFAA violation. That said, there's a difference between a public website such as LinkedIn and a host that just happens to be reachable over the internet, so I'm not sure it would be fully applicable.
