As far as the click fraud goes, that&#x27;s not unique to Yahoo, I constantly see this issue with Facebook, for example <a href="http:&#x2F;&#x2F;www.businessinsider.com&#x2F;facebook-advertising-fake-likes-2014-2o" rel="nofollow">http:&#x2F;&#x2F;www.businessinsider.com&#x2F;facebook-advertising-fake-lik...</a><p>The infrastructure issues may come down to the fact that scaling up large platforms is not easy and they have trouble attracting top talent to oversee this stuff, but that&#x27;s just a guess.<p>I feel a lot of nostalgia for Yahoo, I hope they can turn things around. They have the money and brand to be successful but their margin for (continued) error appears to be very thin these days. I hope their next move is a smart one.
