When I see a card magic trick, for all intents and purposes it "appears" magic. Once I learn _one_ card trick, I start to realize it's not magic. Regardless if I can prove anything or not.

This same applies here with ghosts. People needed to know they _could_ be fooled, how it was done doesn't matter, because people were being scammed and were afraid of things that weren't ghosts.

Proving something is a ghost has never been done, so ghost scams is a good thing to educate people on.
