As a small point of procedures, no one is sending an actual signature.It therefore would provide a modicum of better assurance for signatories to send the email that declares their signature directly to the ISOC President rather than to the person initiating the recall.
If you're concerned that some of the 20 people who Olafur says signed his petition did not actually do so, please say that. If there's some other problem, what is it?
Or if you're worried about unsigned or forged mail, why are you assuming that any of the messages on this list are real? The list software uses only the easily faked From: line to verify senders.
