UPDATE 11:44 PST:
We’ve found the source of these ads and they should be stopping shortly. We apologize for the poor experience that some of you have had as a result and thank you for your help and understanding.
Wanted to drop a quick line about some ads that have recently shown up that have auto-playing sound. These ads are obviously a major intrusion to the Blip.fm experience and we in no way ever intend for ads such as these to be shown on Blip.fm. However, despite our best intentions and requests to our ad partners, sometimes they slip through. We’re working hard to track down and remove these ads and have already contacted our ad partners. You can help us by sending us screenshots of any such ads and your geographic location (some ads are geo-targeted)in an email to firstname.lastname@example.org. Hopefully by the time most of you read this, we’ll have already gotten these ads removed, but we wanted to make sure everyone was aware of our official stance on this.
Yan & the Blip.fm crew
