I love how you claim to feel guilty every time you take over an account, and yet continue to do it.

You may not have written the policies, but you can certainly choose when to enforce them. You waited only a week for Soundcloud, even when you knew it was ridiculously short. For linkedin you went and 'politely' asked the active owner to transfer, telling him to his face he didn't have to, and when he refused you still went to check if you could force it by using a ToS.

Don't hide behind the policies, you are making the calls.
