You get revoked if you don't pay the lousy annual fee. It's not hard to get revoked, and it's not hard to get unrevoked.
The CD holders never take the shell, at least not NIR Group who gave these kids a lot of money.
As far as Sivan, he might have just resigned and said bye bye. Or he could have abandoned the shell.
The answer to it is to ask him, which I will. If he abandoned it, I know a group that will sue him and get him off his tush.
