Spyware

Today I received an e-mail offer from Tech Republic about "Someone in your office is making you look bad". The link for this offer is from doubleclick which is spyware. They want to track me unknowingly. I spend a considerable amount of time removing spyware from my system and do not appreciate offers from anyone to "load another example" on my equipment. Why do you support spreading this spyware activity and tell us your thoughts on this. I'm personally tired of companies who think this is OK under the guise of "providing a better computing experience"
