Linode will send you a confirmation email if you access the admin panel from a "new" IP. This guy must have had his email address compromised as well.
Looks like a class spear-attack.

3 compromised emails? Very unlikely. They are all major contributors to Bitcoin, I think they know a little more than using the same password everywhere.
Linode will only send you a confirmation email if you enable the feature, otherwise tough luck. It's also been confirmed by the vice president of Linode to be a fault on their side.
More plausible to have broken web UI security than an entire bitcoin-community-wide targetting.
The attack was not via the consumer facing admin panel. It was the internal Linode customer service interface.
IF you have the IP whitelisting feature enabled on your account. It is not by default.
