This used to be the case in Dubai when I used to live there. The defacto classifieds website in UAE is called dubizzle (dubizzle.com) which is a subsidiary of OLX. People used to use similar (in fact, worse) haggling tactics to get things for cheap. Couple this with spam and selling an item becomes a nightmare. On the contrary, I have had a far better experience on Kijiji and Facebook in Canada.
