Agents are not permitted to friend suspected tax evaders using false information; however, public information is perfectly acceptable. In the past, collections agents were aggressive enough to appear at residences, places of work and schools. If you thought old school debt collectors were tough, think of today's social media wielding bunch as the Terminator 2 version.

While they're unlikely to kill your next-of-kin after questioning them, they can garnish your family's wages and slowly lure you out of hiding. If the group has just caught on to Facebook and MySpace, imagine the power they'll wield once they start using facial recognition software and people search engines like Spock and Pipl. You've been warned. Pay your taxes on time and avoid an audit.
