How to pimp, okay.
The reality is that we're constantly fighting against issues and content like this. It's a constant effort to identify the context within which there are comments in a video, and then to create what we call a “classifier”, which is an automated system to identify them on a broad scale.
If you see content like that, there is the opportunity to flag it right there on the YouTube video on your mobile device or the page. We use that as a signal to recognize that, wait a second, there is behaviour here and content that needs to be removed. Obviously, that's something we don't want in our system.
