You action was a necessary cause of their deletion and therefore you are one of the directly culpable persons destroying the long tail of knowledge.
I am no expert here, but does one person tagging something for deletion make such an impact? He must have convinced the administrators by only good arguments (like lawyer arguments, which are not necessarily moral or anything, just good enough to win the case).
If we can trust the administrators for putting up something, we should trust them for taking something down.
