Not sure who the market maker is but I do agree with you in regards to manipulation. Some people are long and others day trade. Probably there is a few out there that are doing doing both. I am sure that there are a few traders out there that have made out like bandits day trading ZEN. But then again, anyone has the same right to do whatever one pleases.
I am long ZEN since the early days. Would be nice to have closure on this so we can move on.
