not a penny spent, i was using 10x isdn 30's 300 lines calling every 2 seconds, and disconnecting as soon it is got a status code, a tiny number answered, but i got $xx,xxx for cleansing that call file. i was on night shift that night. lol was a busy night. i actually got a call from thus eventully, the telco, saying there was a problem with there equipement, and apologising for any outage. there wise to this now hehe.

a friend tried it on mobile numbers a bit later, just a 50k sample list. he didnt setup properly and had to explain to the financial director why he got a bill for 15k on mobile calls lol

i once sent an email to the cia saying that i could busy out any local exchange in the world, for a fee ofc lol
