TheOtherChimeraTwin writes: I've been getting spam from mainstream companies that I do business with, which is odd because I didn't give those companies my email address. It is doubly strange because the address they are using is a special purpose one that I wouldn't give out to any business. Apparently knotice.com ("Direct Digital Marketing Solutions") and postalconnect.net aka emsnetwork.net (an Equifax Marketing Service Product with the ironic name "Permission!") are somehow collecting email addresses and connecting them with postal addresses, allowed companies to send email instead of postal mail. Has anyone else encountered this slimy practice or know how they are harvesting email addresses?
