bitcoin.me aka noagendamarket or theymos don't seem to be in control of the funds of GLBSE users - those guys do NOT deserve a scammer tag.
It's nefarios responsibility to return the funds and the shares to the users of GLBSE. He clearly controls the domain name glbse.com.
Innocent until proven guilty!
Scammer tags are more like warnings than findings of guilt.
If that's the case those "scammer tags" should be renamed.
A person can now open a 'company' and name a sockpuppet as CEO. Then when user funds get large blame the CEO for running off with the money. In the bitcoin world, when times get tough no one needs to blame Chinese relic dealers for stealing the funds. Just claim he is the CEO now.
