Referral trains

More often than not, I see people who have already been users of a site (based on the comments section of their profile that EVERYONE can see) hijacking referral trains. Referral trains are in place for NEW users to sign up under each other, not a place to spam your referral link. If you want to get your link out there, make an informative post to bring people in.

I understand everyone wants to make money and supplement their income but this is getting ridiculous.
