The "how" of sockpuppetting relies on the anonymity of the internet. I'm not going to tell you how, 'cause that might lead to people doing it.

As for how it is exploited, TDW used another account, namely Jr., to mirror his own opinions in most cases. Looking back, it's kind of obvious, but still. Doing it is a serious offense, so... don't.
