A pointless waste of time. The first day gives 40-60 links, which averages to about 50 cents. Then you either need to bring in a ton of referrals or add people or news on Facebook, which, as they say, will increase both the cost of likes and their quantity. But it's pointless; I personally had 10 referrals and neither the cost nor the quantity increased, and links come in at a maximum of 2 to 5 a week! So you decide for yourself.
