Why would this kind of penny stock increase so much in value?
Disregarding the particular example and focusing on the actual questions: YES, definitely, the whole concept of "pump and dump scheme" refers to the many cases when this was intentionally done; Everything has a limit, but the limit can be quite high, especially if starting from a low value (a penny stock) and if the stock is low volume, then inflating ten or hundred times over a real value may be possible; and any value might be infinitely times overvalued for a company that turns out to have a value of zero. Yes, unless it's done very blatantly, you should expect that the "inflator" has much more experience in hiding the signs of inflation than the skill of average investor to notice them.
