Two quick, random ethics questions disclosed, referring, ethics, needed, actual

Spongebob

Hey, just a couple of last minute questions:
1) To what extent do referral fees need to be disclosed? Is saying “I do get a fee for referring you to this vendor” enough, or does the actual fee need to be disclosed?
2) Why is it okay to say that results are simulated, in a small-print footnote? I thought such disclosures needed to be fairly prominent.
Thanks
