I use individual email addresses for all sites I register on. Like Zimbra forum.
Today (2011-06-04) I got spam on this unique address from do-not-reply@select2gether.com. A person (nina.crowth) requesting to add me as contact on Select2gether.

Because I use individual email addresses, I suspect my email address here on Zimbra forum has been compromised.
Anyone else got spam from select2gether?
