I suspect it might be the remnants of that defunct P&D group, consolidated and re-formed, manipulating the price low while they accumulate a new stash, with the intention of pumping then dumping again. Misplaced hope of recovering some of their lost funds. They should consider that it didn't work out well for them the last couple of times they tried it here, and that maybe they should move on to some other coin. Perhaps one of the SCAM coins would be a good target?
