Cheat codes are inherently unverifiable as to their origins, and in the same way we can't stop people from lifting codes from GBAtemp - it's not really possible to prove codes that show up here are taken from other places.
If you can prove their origin and that the creator explicitly doesn't want the cheat codes here I can work from there. But for the most part we should try to credit the creators.
