Photonlight Email Leak

I bought a product from Photonlight in 2002, and have been on their mailing list ever since. I last received something from them on 30th December 2009. Alas, now I’m also receiving spam to the address previously only known to them.

Both Photonlight and Slimelight use iContact.com as mailing list providers. I spoke to iContact customer services via web-chat, and was told their privacy policy is to not share addresses with anybody.
