SPAM in the future

Recently I have contacted employers via email and have received automated emails back from their email addresses telling me to respond to the email if I am not spam.  Companies and individuals are becoming smarter about blocking their spam emails.  This is making it harder for spammers to do their work.  Although you may not think you are receiving less spam on a daily basis, Internet servers are constantly trying to block these useless advertisments.  SPAM may never be completely gone, but more people are learning how to ignore it and therefore causing spammers to create other ways so they can reach millions of people.
