I'm not the original author, but I have no doubt that "claimed to GLBSE" refers to completing the claims process at GLBSE. Friedcat refers to (1) those that completed both his claims process and the claims process of GLBSE, (2) those that completed only his claims process, and (3) those that completed only the GLBSE claims process. That should just about cover everybody with a stake in the company, except for those whose shares were not even originally on GLBSE...

Edit: And a big round of applause for friedcat and friends!
