Details:
Recently reactivated my POL ID and started receiving spam from SE for games other than FFXI. I did not opt-in, was not told I'd be receiving spam. Had to click the "unsubscribe" link from within the email to unsubscribe from a mailing list I never knowingly signed up for.

Steps:
1) Deactivate POL ID.
2) Reactivate POL ID.
3) Receive spam.

Date & Time:
1) Deactivated September 2014.
2) Reactivated March 2015.
3) Received spam 3 days later.

I hope this doesn't require another phone call to your mail provider to get sorted out. The folks at Yesmail take spam seriously and would likely be very interested to hear that you're signing people up for marketing-based mailing lists without their knowledge or permission. Be a good Internet citizen and make it opt-in.
