Well if it's something that the software engineers are expected to implement, then they're going to have to be told about it. If it's not, then it seems out of the realm of software engineering.

Eventually it would have to be told to a CTO, president or Vice President it some technological product, software architect, etc. Software Engineers generally need to understand the use case of a product to be able to develop something effective. It would be exceptionally difficult to convince someone to code something that creates fake profiles of people who don’t use your site and no one have any idea that that’s what’s happening.
