If it was blatantly pornographic, there's a very good chance you could be permanently banned. Don't post inappropriate ads publicly. If you're posting it to report the ad, send it to Paril privately.

We can exclude them, yes - we cannot however just point at an ad and destroy it at will. You may want to re-read my second message. Like I said, the provider itself (the third party that we deal with directly) knows what is and isn't allowed and what our audience is. Keep in mind that the ad provider gets money based on interest, clicks, etc; they are fully aware that the 8-12 demographic (which is pretty high here) aren't going to click these and they would lose money by showing them. They have zero incentive to have these show up. The problem lay with the providers that our provider deals with. My assumption is that the information is relayed to the parties who are interested in advertising on PMC (or it's just a global network with the name of the site not explicitly mentioned, which may also be what exasperates the issue), and they are responsible for making sure that they follow these guidelines else they risk losing their privileges to advertise on the network.

That being said, exactly what determines what ads appear for you is based on factors that might as well be trade secrets. Search history isn't as easy as just "what I googled" - search history is data that is compiled based on many many factors that aren't tied to you DIRECTLY, but rather your IP address and geographical location. If somebody else had your IP address in the past (dynamic IP addresses for instance) you will get varied information based on stuff that people that used to be "you" visited and searched.

It's not about what you search but rather what you visit. Google and other search engines have strict policies about data shared with third parties; they generally don't do it (after all, it's more valuable if only they have it. Advertising is a business for them). When you search for something (say, "dental work"), that data doesn't get fed directly to anybody, but once you start clicking on websites on that search list you are exposing yourself to potentially hundreds of providers who have trackers on the pages to check what kind of sites your IP address is visiting. Eventually, later on in the day, you will start seeing more dental work-related ads show up on sites that have trackers dropped on those pages.

Whether you're incognito, whether you have ad-blockers or whether you use Google/Bing/Yahoo, it really doesn't matter; this data is still being fed to companies that are interested in it.

The issue with the virus Java ads is that there's clearly somebody who is misusing their service to a pretty excessive point. We've reported at least a hundred domains to the provider and usually I only hear about any specific domain once and it is gone by the time we've reported it. Like the shifty people who push content developers to use shoddy, adware-ridden installers, it walks a very dubious legality line and the best we can do is just report it hoping that they will be able to prevent them easier later on down the road.
