Are you seriously calling this a "passive placed cam"?

Regarding cam strength and potential for failure. The ultimate strength of a well placed cam is normally in the wire not the lobes or axle(s).
So placing small cams in positions as described is unlikely to result in a stronger or more secure placement that in a regulation parallel crack. Of course not everything is a regulation parallel crack, placing a cam behind a slight constriction is fine.

Since when are Zero's rated for passive placement? EDIT: It seems you are correct according to WC. However I don't trust the TINY cam stops on my #2 Zero.

I hope he isn't! That cam looks fine.
I agree that passively placed cams are largely useless. It was a marketing feature that arose out of dual axle designs. That said most small cams aren't rated for passive placements. (For me, small cams are << BD #0.3)

Ok, I was just confused since in one sentence you were talking about that particular placement, and in the next you were talking about passive placed cams. Moving on!

All zeros, in fact all the current DMM and WC cams are passively rated ... The brit make em that way for a reason
Folks who climb in limestone like to work their cams into pods, constrictions and other places where they wont come out ... And act as passive pieces if the active placement slips, which happens on limestone sometimes
Out heres there are a few parallel internally flaring cracks where a hex would be bomber, but no one carries those anymore ... A passively rated cam slides and locks right in ... A nut would just rattle out
As to "just use a nut" ... On multi sometimes you already used up the appropriate sizes nuts ... And for larger constrictions who brings up the largest sized nuts anyways .... Bringing up an extra green/red camalot is generally more useful
