You might say that spam supplies me with information. If I want smut, I'll go surfing on my own or buy a book of erotica. Spam is also a negative way to promote your business and not as profitable. This gives you 1,000 purchases. That's not a number to be proud of.
Business needs to advertise to survive.
That's a given. I don't feel that spam is a positive way to advertise. Create a banner ad and place it on related interest web sites.
