I registered at Magenet in around 2012, and since that time i cashout more $350
Withdrawals are made till the 5th day of every month

They paid me several times and they respond my support tickets quite quick.

The people are really buying the links from my site. Usually they buying only ones that has some pagerank. One usually earn like 0.6-2 usd per link monthly. (Pagerank 0-2) page.

Magenet appears to process withdrawals monthly, at the beginning of each month. Just request withdrawal once and be patient:

October 03, 2014 - $176.34 payment to paypal received
April 19, 2014 - $50.59 paid
November 6, 2014 - someone is saying he got paid too
January 12, 2015 - $135 paid
March 2nd, 2015 - $50 paid
April 1st - $50 paid
Jun 2nd - $54 paid
jun 9th - $51 paid (within around 7 days of request!)
jul 3rd - $51 paid (within around 5 days of request)
Sep 7th - $54 paid (within around 14 days of request)
another payments there. i request payment like every 1 or 2 months. if they stop paying i should update this topic

So far Magenet is number 1 earner for me regarding backlinks sales. One should have pagerank in order to get backlink offers.
