Assuming those 19M outstanding shares represent about 50% of the actual ownership value available to the company (a total guestimate based solely on knowing that Nexon is the largest shareholder at about 15%, other than the owning family whose share I don't know), it would take getting 10% of those 19M, or 1.9M, shares to gain even a 5% stake in the company. Going even smaller, on the off chance that even a 1% unified voting bloc of shares would be enough to influence their decision-making, that would still be 380,000 shares the community would have to buy and then elect a single proxy to be out voice.
380,000 shares at $200/share is $76M.
Seventy-six million US dollars we'd have to raise to gain a 1% stake in the company.
Even if the "19M outstanding shares" represented a 100% interest in the company, so Nexon has 15% or so of THAT, to get 1% of it would cost us $36M US.
At 20,000 signatures on the petition, that would be $3,800 US per signer of the petition, on average. I don't know about the rest of you, but that represents sufficient of my total spendable assets (i.e., not my car or my TV or my computer and the like) that I would not be willing to do it unless we had a guarantee of everybody else doing so, and even then...it's a massive risk.
