My band's Farcebook page is being inundated with things like this...
The scammers get a temporary guest account from FB (Guest 4756 in this case); the temp account lasts for 24 hours, then disappears. If you click on the link, they gain access to control your FB account. Not much you can do about it as the guest account, now with access to your account, has gone.
It's happening to loads of bands that we know, apparently it has been relentless this whole weekend. There are some absolute wucking fankers out there.
