I have a very good memory for basic trivia like your online handle and your mom's name.
You don't practice very good information hygiene, and when you were desperate and when you were trying to start a business, you put all your contact information out on the web where it can be Googled. Like, in public.
You were a rat bastard to My Virtual Nephew.
Congratulations, yet another set of bill collectors know where to look to start finding your valid information.
