As long as you don't tell any human being that you are doing it and or they don't discover that it is you doing it, it's fair game. It's actually pretty gross how many businesses do just this. There's a radical group out there that goes after them magically speaking. xD 

Won't be in this RP though. If you have a character with that in his background PM me and I'll happily tell you about them. That group can be a part of your history. 


Edit: They don't care what you do moral wise as long as you don't reveal anything to them unintentionally or intentionally.
