Well, a majority of the coins were stolen from Gox. Glasswalker got too busy to keep things running and the operation was closed and liquidated. People who went through the share claim process after GLBSE closed received a dividend of about 0.0115 BTC/share when the operation was liquidated, approximately in mid Feb, 2013.
Would that be still possible to do now, how do you think?
Maybe, if you contact Glasswalker. In the email I kept from mid-Feb, he said that any funds not claimed 30 days from mid-Feb would be forfeit, but it doesn't cost anything to ask if he's still holding the funds.
