No, never ever "BUY" referrals, these are scam websites wanting your money. Beware of any site promising
you referrals. Nobody would share thousands of referrals with you, that is common sense.
There are many ads on PTCs that claim to sell you direct referrals to any PTC, beware !
You will have to get referrals on your own. Getting them is not the hard part, it's getting ACTIVE ones.
So it's preferable to avoid simple link advertising, or the equivalent of cold calling (for telemarketers) and instead
have your own custom page with sort of a "pitch" first, explaining what CS, what it is not, and what to expect.
Try to inform people what they are getting into and be honest (important). You might get less referrals but
more quality ones ! Even so, a lot of people are in constant search for ways to earn online and most people
have high expectations (miracle seekers, get rich quick seekers, etc.) it's not going to be as easy getting
referrals to CS as it is getting referrals to HYIP, matrix, and other ponzi schemes.
