I've filled out the inactive Profile URL form twice already, the first time being over two weeks ago. The FAQ states " the account is inactive, the current owner of the Profile URL will be sent a heads up email, notifying them that their details have been requested by another user. After receiving this email, they will have 48 hours to sign back into their account to retain possession of their details. If they do not sign back in within 48 hours, you will receive an approved request notice, confirming that the requested changes have been made to your account."
It's been two weeks, leading me to believe no one at Soundcloud is even reviewing the form.
