Had account guardian, recov's and all other methods of account security still got hacked. Requested my account to be locked until I could recover the account, took over a week for Jagex to lock it. Just enough time to cancel bank pin and lost every single item that was tradeable. I had atleast 600m cash-pile and at least 1b in items. I would have just recovered the account as soon as I noticed my password was changed but apparently my registered email was changed. :/
