I've over 100 signed up via my Xomba referral link and even 10 via Triond but only 2 via hubpages. I've read somewhere that hubpages referrals are a complete con and my personal experience of it seems to stand in agreement.
Why are you asking a question if you've already made up your mind about the situation?
It sounds like you aren't targeting your HubPages referral link to people who genuinely want to join the site and write. Referrals won't earn you anything unless you sign up people who then make a good quantity of really good Hubs.
Out of all my sign-ups, I've got a few good Hub authors in there, and I earn over $100 a month just from them.
