Why would anyone need "proof" at this point?
This isn't a court of law, it's an "investors" forum. The guilt by association, inferences and suspicion are extremely relevant for any stock. Conservative investors who wait for absolute proof of success before buying a stock usually miss out on a big part of the run-up, but they avoid buying scams. Riskier investors who buy on solid evidence stand the most to gain and limit their risk if their DD was also solid. But those who buy on emotion with no proof or even solid evidence of success, and then wait for absolute proof of failure or criminal activity to sell...
now that's a recipe for "DISASTER"!
You better be ready to pull the plug on the way down before absolute proof, or you won't have a plug to pull...
Of course when one goes from five dollars to five cents most should have already figured that out... but it looks like some still have not.
