This site harvested my old kijiji ad for an item I sold months ago. Now people are harassing me trying to buy it after it has been sold. Posted my contact info without my permission. No way for me to remove my ad.
Don't use OKZ.ca as you will likely just piss people off asking about already sold items.
Whoever cane up with this website is some bottom of the barrel scum. It's likely illegal as well.
