The difference between teaching someone to wipe an teaching someone to commit a federal crime are two different things. While it is entirely unsporting to cheat on the level of wiping, you aren't actually commiting a crime. And honestly, how many people don't know how to wipe? Sure it may take a few tries to figure out how to do it more without anyone noticing, but everyone knows the basic concept, so they aren't revealing any secrets on cheating and getting away with it that people don't already know or won't figure out very quickly. And I'd actually have to go with Meph on the helping of refs on the field when they try to spot cheating. I say, leave it, and if someone uses the information for evil, bonus ball them.
