You are paying to have your ads seen by real people to create brand awareness and get the multiple touches that will result in conversions. If those ads aren&amp;#x27;t getting seen then obviously they are not effective.</text><parent_chain><item><author>acchow</author><text>A bank spends $1000 on advertising and it ends up with dozens of accounts and credit cards opened and they decide it&amp;#x27;s a good ROI.

It would be like if you bought a bag of rice, but after you opened it you discovered that half the grains were in fact plastic. Of course you could  still filter out the fakes, and you&amp;#x27;re still left with a half bag of edible rice, but in the end that&amp;#x27;s not what you thought you bought. In other words, this is fraud, and marketplaces fail if there&amp;#x27;s too much fraud.</text><parent_chain><item><author>acchow</author><text>A bank spends $1000 on advertising and it ends up with dozens of accounts and credit cards opened and they decide it&amp;#x27;s a good ROI.
