can a Facebook advertisement be considered a thing of value?
Congress could not have used a term that is more inclusive than "
thing." If the drafters of Section 8 had intended to limit RESPA's ban to fees, payments, compensation, or money described in any other way, they would have used a narrower term.
Since any
thing can be considered a
thing, the only remaining question is whether or not it has any value. Actually, since it's impossible to prove a negative, there's no way to argue "it's a
thing, but it has no value." The very fact that you want to do it proves there is value.
