Yes, I also believe toxic financiers like Asher, JSJ, LG Capital, Vis Vires and the rest use similar tactics, especially in the low trips. Through associated third-parties, they will come in and buy up 200-300MM shares at, say, .0002 and .0003, in order to generate some buzz that "something big is coming" (helped by a sudden influx of new posters pumping all over the board). Then as retail starts to buy in they begin dumping tons of shares they are converting at .000055 or so, until their note is done and then the pumpers dump out as well. They "create their own liquidity" in other words. It's worth spending/losing a few thousand (or tens of thousands) in order to create enough liquidity that you can sell $50-100k of discounted shares.
Hard to prove, but the circumstantial evidence is overwhelming IMO.
