False
NightmareStresser ran "over 8 years" with "no vanishing acts"
Assessment
This is the service's own marketing, preserved from its seized site by The Hacker News. The same report states a domain under the NightmareStresser name was already seized once, in December 2022, as part of the same Operation PowerOFF program — meaning whatever ran in September 2026 either regained a seized domain or rebuilt under a related one, directly contradicting an unbroken-uptime claim.

Contradicted by primary sources. Reserved for claims checked directly against the authoritative record — an advisory that does not exist, a catalogue that does not list the entry, a directive that says something other than what is reported.
