How is that "nefarious"? It's not like using a copy nfc tag is giving some players an unfair competitive edge (animal crossing is supposed to be laidback right?). Also, there is a limited supply of any given amiibo and so when one suddenly becomes popular (* cough * Ankha * cough *) many players get priced out.

"I heard of some nefarious characters" is code for "I used my Android phone to write NFC tags and I will do it again".
