So Facebook have made it so that you can now delete an administrator even if they created the page!
In some respects a good move as it means Facebook pages can now be transfered from one user to another but there are a fair few rogue admins and companies out there that have deleted owners and may now possibly hold them to ransom until they pay up/or are disputing ownership.
I’m sure they could have found an easier way to change this and put a verify step in too so that people don’t lose their business pages…
I’m pretty sure someone out there will find a way of making some extra money out of this as you suggest, but I think on the whole it should be for the greater good. As you say the ability to transfer the fan page alone is worth it.
Maybe the next step should be facebook finding the unused fanpages that have been discarded over the years, contact owner and ask if they want them deleted?
