Google AdSense disabling arbitrage publisher accounts as of June 1st

JenSense.com: "Numerous AdSense publishers have been receiving emails from Google the past couple of days stating that their use of their AdSense account is an unsuitable business model and that accounts would be disabled as of June 1st, giving publishers about two weeks notice to prepare for the loss of the AdSense accounts... and since it seems that arbitrage publishers are the ones receiving this account disabled email, to give those publisher enough time to shut down accounts or use an alternative source for their outgoing traffic."
