"You can't cheat an honest man."
Even calling it Pump&Dump is a bit misleading. Other people might think
they can also "ride the spam wave" if they have the right market timing,
sometimes called the bigger fool theory.
Like scientists being fooled by psychics, the research assumed the
marketplace quotation data accurately predicts what the trades "would have
been." But they didn't actually make those trades.
In some cases, the game is rigged even worse than the published studies
found. In very illiquid markets, sometimes almost everyone except the
mark(s) are accomplices. With accomplices on both sides of the
trades, quotes and volume don't mean much until the mark loses his
money. Then whose order actually gets filled?
