So I'll ask it again. I had the exact same idea while reading the thread again, and I forgot I had the idea the 1st time & posted it.
For example, in a drug transaction, it's not enough for law enforcement to have evidence of payment, or evidence of the delivery, they have to be able to connect the two in order to prove a transaction has taken place.
In the situation of "pump & dump". If one person pumps for no special profit, and someone else just magically knows when it's time to dump, wouldn't (for all the scared little girls in the thread) law enforcement have to show a connection between the pumper and the dumper in order to prove a crime had been committed?
My new idea:
Investment website. Scrape 4 financial guru's content and include your own 5th shill. Publish the gurus. Maybe the shill echos the gurus until one day the shill starts pumping & pumping.
Meanwhile, in a completely unrelated area of the planet, behind 2 firewalls and 7 proxies, and anonymous person sells-off a stock that coincidentally happens to be the same stock the pumper has been pumping.
You could even go a step further, and give "advance notice" of the pumped stock to special members, and then an emergency order to sell immediately after the tier-1 investors have sold-off. The SEO is used to promote the investment club's website.
