This will be awkward to implement but not for the obvious reason of avoiding automated fraud. In some jurisdictions, it is illegal to offer kickbacks for certain products and services, if not all. For example, in the UK, I believe that it is illegal to offer consumers cash to accept a line of credit. I believe it is for this reason that UK credit card affiliate programmes specifically prohibit affiliates from sharing revenue with consumers. If you offer a cashback programme to end users, you'll have to forego some lucrative advertising and/or explain to end users that some offers in some jurisdictions don't provide any cashback and/or explain fraudulent clawbacks to a large number of end users. In addition, the exceptions will be awkward to implement, maintain and administrate.
