The number of duplicate postings by the same advertisers is completely unneccessary and actually prevents Joe Public from finding genuine people looking for cars.
As equally infuriating are for sale ads where for example 73,000 miles is entered purposely as 73 miles, so when you try to filter a search by lowest mileage first, it's utterly pointless.
Whenever you see anyone doing anything stupid/irritating in the classifieds (including incorrect milages, prices or duplicate adverts) then just hit the report button and we'll get it sorted.
