Follow Spam
As defined by Twitter: Follow spam is the act of following mass numbers of people, not because you're actually interested in their tweets, but simply to gain attention, get views of your profile (and possibly clicks on URLs therein), or (ideally) to get followed back. Many people who are seeking to get attention in this way have even created programs to do the following on their behalf, which enable them to follow thousands of people at the blink of any eye.
The TSD Method does not promote follow spam in any form, as a company with a public image, it is shooting yourself in the foot.
