Who is getting the leads from your listings? Trulia and Zillow

I have advocated only letting  lisitngs be put on Realtors and sites controlled by Realtors since 97, was told by boards around the country that we owe it to our customers was even fined for a listing being misrepresented on one of these sites because it was sold and not active. We need to pull em from the newspapers as well. The only place our listings should be is Realtor sites and sites controlled by realtors, then we won't have to buy our leads and we can safely put control back into the market. We owe it to our customers to have correct MLS data whereever our listings are presented.
