FWIW, I searched the vast Internet library last night, and came away with little understanding, but much speculation (mine).
"Harbor City Capital" is relatively new, and there are links which seem to predominantly go to the company itself, or "articles" about the company and its founder JP Maroney. What I surmise is that the author is working the internet (an author on HuffPost?), and knows how to feed articles to sites, increasing his hits, and so forth. He does have a paid google ad, and that helps push other results further down the page. Nothing illegal about any of that.
But what of his investing arm, "Harbor City Capital"?? Combine the name with scam or ripoff or complaints, and you can find a little about what makes the company tick. Complaints seem to include $25,000 and waiting for a client's check before returning the investor's money after a complaint.
I am amazed at how a company can still get their positive search hits as well as an ad or two on the first page when you search for complaint and ripoff.
Lastly, I am too suspicious. Why would someone post about an obscure investment, when clearly there is no one at E-R jumping up to speak about this great investment? It makes one wonder.
