I'm not sure if you're aware but there is a dodgy Flash banner at the bottom of your website that blasts out "Jingle Bells" for 10 seconds. I thought it was an April Fools' joke at first, but now I have to mute my audio every time I browse the site.
I don't think these Flash ads should be playing audio to the end user, and I'm certain that they are in breach of the AdChoices Terms and Conditions.
Here's a screengrab of the ad.
It links to ads.creative-serving.com and the redirects to aldaniti.net, which is a scam website.
Perhaps you should report this to your advertisers.
