Generally speaking, idle unpaid accounts like this are either sold by the creditors to a third party debt collector, resetting the clock, or they will sue you for the non-payment to get a judgment or lien, resetting the clock.
The only sure bet is bankruptcy, which will drop off your report after a period of time that varies from state to state in the U.S. (generally from 7 to 10 years). Not sure is this applies outside the U.S.
I had to check the community and link, because I could believe he would say something like this.
