And yours does? All you’ve posted is a screenshot of elements you claim Twitch’s player injects. Where’s your hard evidence? Where’s the working example? Where’s the isolated player proving it’s them and not something else you’ve loaded on your website?
I’ve also updated my example. The “streamerhouse” stream is live 24/7 and they also run ads often, and I’ve never seen Twitch ever inject elements onto a page (nor would they, as ads are playing videos inside of flash). Why would Twitch inject anything into the DOM through Javascript?. Even if they were, you can easily prevent that with “allowScriptAccess” set to “never” in the flash params.
I deny the issue since it doesn’t make sense. Twitch wouldn’t execute arbitrary code on a site it’s been embedded on. In addition, as far as I’ve seen Twitch makes use of Google’s DoubleClick ads network (not AOL’s Advertising.com) since they sell their own ads at http://twitchadvertising.tv.
