I found this fascinating quote today:
Since this year a lot of improvements happened in Neobux. For who doesn't know about Neobux, it is the No.1 Paying Paid to Click Site. The Color Coding which is only available on if you have the plugin Greasemonkey on your browser was made available now all users can monitor average clicks of their referrals. Reduction in cost, for example the cost for rental, renewal and autopay of referrals from $0.30/$0.009 to $0.28/0.0085, this is for standard members and for premium users the rental queue for 25 referrals goes down from $10 to $75 dollars. another important change was being able to privately message your referrals. A lot were taught by Neobux Admin on how referrals work, heres a summary after a referral have been recycled, it will be monitored for 15 days and if his/her activity is back on the general rule of 10 clicks in 5 days, this means when we rent referrals or recycle our referral we are guaranteed to get clicks. Now another improvement which really gives me joy, being able to know whether your referrals are doing a good job. This new chart feature an "Projected Averages" this new bar will appear below your direct and rented referrals chart. On this bar 2 pinters can be seen, on top the blue triangle for "Projected Average for Today" and the other below is the white triangle for "Current Average for Today". I don't know how they calculate the "Projected Average for Today" but this is your daily target to achieve or surpass. "Current Average for Today" is definitely your daily average no explanation needed. Also this bar is divided on colors (red, yellow and green) which is bad, average and good, respectively this is based on how you setup the color slider found in the referral listing.
