hijacking Facebook

The above article talks about how a group of people called "Control your Info" has been "hijacking" facebook groups to show the Facebook universe that it can be done, basically. What they do is go into a group where an administrator has stepped down and take over. When an administrator of a group steps down and does not appoint anyone else as the new administrator then anyone can take over the rule of the group. I am split in my opinion of this hijacking. On the one hand it is showing a flaw in the Facebook system, but on the other hand why does this group feel the need that they have to do this? Why not just write to the Facebook creators and inform them of this flaw rather than filling the group with spam posting and potentially changing the cause of the group? My thoughts are that in any Facebook group the control should only lie in the hands of the administrator or administrators. When they step down they should either appoint a new administrator or if they don't, the group just stops existing. I don't like how these people can just come in and start posting whatever they feel like in groups that they really have nothing to do with. When it comes down to it, they are just "hijacking" these groups just to do it. It could be a simple process by writing to the creators but they are going about it in a way that is taking over something that isn't theirs.
