Nonspontaneous at all temperatures - whats the truth?

Nonspontaneous at all temperatures - whats the truth? or which definition for the DAT?

So Dr. Romano's class and probably the Destroyer as well taught us that +deltaH & -deltaS would be nonspontaneous at all temperatures

In Qvault, I just saw this as extraneous info in an explanation - Note that according to thermodynamics, no reaction can be considered nonspontaneous at all temperatures. There is no theoretical upper limit to temperatures on the Kelvin scale. There may be a practical limit, if the product would combust at the temperature it becomes spontaneous

whats the verdict?

+delta H and -deltaS is always non-spontaneous
i heard datqvault has some errors on explanation?? maybe thats why
