The classified section is for people who want to sell their personal stuffs like their car or their furniture because they are leaving.

If they make money out of it ... or making business and using classified in this section ... i do think they should contribute something to Qatari as a site owner. Maybe sponsoring the site with their company logo or something like that. Not using the 'free ads from the site' to make a living out of it.

Then again ... thats just my opinion ...
