@apsurd - thanks for the mention. You are spot-on about the white labeling - we do offer the ability for a company to host the referral page describing the offer on their own site with their own branding (rather than RefMob's.)

Also, with respect to Facebook and Twitter - all we are trying to do is make it easy for people to refer their favorite business to their friends (not anonymous people) and share the referral bonus with them. They don't have to use FB or Twitter - for example they could just share the link to the referral page on their blog, or on a card, however they like. -Don
