Nah. OTC "filings" or not, GRDO remoains as obvious a scam as you're likely to be unfortunate enough to see down here at the sleazy end of the penny stock markets.
There's a whole lot of stock pimps who front-loaded prior to last week's filings who will be looking to offload their shares into any volume they can generate this week, so I'd look out below if I were a GRDO speculator.
