It wasn't a spy, it was a high level bob director who decided to leave and isntead of just leaving he decided to have as much fun with it as possible, so he went to the goon "spymaster" mittens and basically offered to do anything with his account.
It is still not known whether the bob director's account was stolen from him or not and what goonswarm did was try to make it seem like this is what happened with his account info.
To answer your question, yeah, despite the fact that you can't really do anything in eve without a 24 hour timer (kicking members from corp/unlocking assets etc.) it is surprising that you can dissolve an alliance with a couple right clicks and the correct permissions.
But yeah despite the fact that goons did virtually nothing to actually make this happen and it was solely a director inflicting as much damage as possible before he left, it is a testament to their ability as a propaganda organization that this story is so wrong and on slashdot, but blatantly slanted and often wrong stories are the norm here. (but hey, at least its not digg)
