Digital publisher blacklists have been around a long time and are already part of the algorithms for most ad servers.  Brands will always ask their ad sellers to avoid any particular, or easily identifiable subset of questionable sites, once the brand is aware of it.

Samsung has a major and very expensive ad campaign on YouTube going right now.

Netflix, Southwest, Target, and Samsung are all are depriving artists by advertising here.

These companies, and their media buying agencies have no clue whatsoever that they're advertising on these sites. They pay $0.25 CPM on ad exchanges and blind remant advertising.

Groupon I'd lump in the knowingly doing it/not giving a flip category. Here's a a screen cap of them skinning Grooveshark: http://www.jealousof.us/groupon.png

well, well, well

groupon supporting blatant piracy and copyright theft?  not surprised

Advertising on Grooveshark does not mean they support copyright theft. It means they know how to reach a wide audience effectively and reasonably. And as of right now Grooveshark is operating safely under DMCA until the court proves otherwise.

This is the most misleading news title I've read all month.  You should be ashamed.

Agree... any website can join an advertising network, it's not the company's fault, it's the fault of the advertising network for not checking the content on the website. Half of these articles lately make me wonder if anyone has a true grasp on how the internet works... unbelivable, but we've been sharing music online since for 20 years now. It's kinda lost its shock value.
