I wonder if you could sue a website for serving you malware.<p>Here&#x27;s my idea for an ad company:<p>* People who want to post ads have to provide their name, address, verified email, and a security deposit(say $500). Larger volumes of ad purchases require either a long history, insurance, or a bank letter to vouch for you. If you load malware anywhere into the system, you get fined and your information gets turned over to the police.<p>* People who want to earn money with advertisements have to provide name, address, verified email, and a security deposit. The security deposit could be funded out of earnings(or not). Fraud is countered by randomly sampling websites and fining offenders if the ad isn&#x27;t visible. Also they get their information turned over to the police if it was intentional fraud.<p>* Security deposits are returned within 1 month after the advertising relationship is terminated.<p>* Fines are paid out of the security deposit, and your access is restricted until you refill the account(possible with an even bigger deposit).<p>* People who are higher risk(from a shady lawless country, no history or background, etc.) have to pay a higher security deposit.<p>* Ads can be either text or banner ads. Anything Turing-complete needs insurance or a bank letter.<p>* If someone pushes through a porn ad to get advertised on the NYT by miscategorizing it, they get fined.<p>Now all the ads are guaranteed to be of high quality, and the websites you&#x27;re advertising on are probably higher quality too.
