how long does a free site stay listed

[stuveltje]

when i had my linksites (ex linksite owner now, but soon again an linksite owner) i removed all the isites which where a year in my linksites, easy reason, i dont want my linksites to big because i wont be able to give them the traffic, so removing the sites after a year out of my database was the solution, i have mention that on the submit page and also that they could resubmit.
