First of all. I actually see a problem with the posters that I didn't notice before. They target lying which is intentional. And intentional acts aren't covered in the ones they're supposed to go along with. At the very least the original ones seem more informative than accusative.

Furthermore if we really cared about the issue of false accusations and informing about consent, wouldn't we not make parody posters but original ones with no reference to these and their specific context but ones in which that problem is seen(eg. Brian Banks)?

Just think whoever put up these made us all look like evil trolls.
