> It is legal threats against you, your family, your friends, your employer, etc... If any debt collector is brave enough to do any of this I'm documenting all of it and suing the everloving pants off of them. Because that is harassment.
With what money?
Just document all calls, save all letters, and get a good grasp of the Fair Debt Collection Practices Act and any state-level equivalent (Rosenthal in CA) -- in CA you get to shoot the violators with a double barrel for federal AND state violations.
Having the major credit card companies increase my APR to 30% in 2009 having never missed a payment on anything in my life, while being backstopped via TARP and having literal 0% Fed/interbank lending rates blew my top off and I decided giving them the finger was my individual right of protest and damn the consequences. Little did I know I was entering an exciting world of learning how to beat the bottom feeders at their own game. Never paid a dime, made about $20k suing for violations, and my credit score was above 700 within 4 years and after everything fell off (7 years) it's like it never happened. But I'll never forget it - was pretty damn exciting to be honest.
