A bit of a long story so bear with me. A few years ago I was struggling for cash and decided to try selling some of my academic papers on Academon. I sent them a half dozen of my best papers, all graded A. They went on sale at Academon for $50-60 each. Authors get 50% of the sale price but you need to reach a $50 threshold before they pay out. According to Academon, they sold one of my papers in 2007 (just after I submitted them) and haven't sold another since. Earlier this year I got curious and had a friend buy one of my papers through Academon. And as I expected, this sale never showed up in their reports. Who knows how many of my papers they have sold and kept the cash for, all while telling me I hadn't met their payment threshold. They are liars and cheats and thieves; avoid them at all costs.
