Refresh rate doesn't enable/prevent subliminal ads. It can be done at any refresh rate, though higher Hz means things can be shown briefer but more likely to be missed. Refresh rate is simply a function of how many images per second it is capable of.
If you're playing video, it will look pretty much the same at any refresh rate (nonwithstanding stutters). On most displays, 24fps means a frame is shown for 1/24sec (or nearest, given refresh rate limitations, 60Hz giving you an opportunity to show a frame for 1/20sec or 1/30sec, but not exactly 1/24sec).
Now, if you're playing game, it has more control over the granularity of the frames -- a 240Hz monitor gives you the option of showing something as brief as 1/240sec (1 refresh cycle), 1/120sec (2 refresh cycles), 1/80sec (3 refresh cycles), 1/60sec (4 refresh cycles) and a variable refresh rate monitor can show you any arbitrary duration that's within its refresh rate rate -- e.g. 1/235.291sec or 1/123.58sec instead of 1/240sec.
However, that doesn't influence whether or not a subliminal ad is more likely to happen or not, or necessarily more/less effective.
Now, this topic is a bit out of left field in the Blur Busters Sphere.... so:
Moved to the Offtopic Lounge for continued discussion.
