Yup, agreed. I guess it depends too on the bottom line and what a cost implication it has, as well as maybe not being as "good" a referral if it's not as close to real word of mouth?

This is also the way my company changed our referral scheme and it makes it a bit more awkward because you have to actively ask for someone's details to refer them, whereas before you got it through folks following the link, which feels less invasive to me
