I'm not sure if the World Cup will be streamed on Dailymotion live, but I found this piece of news interesting:

I'm just wondering if this is implemented for an online video community, will it be abused on sites that are not as strict in their moderating? For e.g. if a live feed of a terrorist execution in Tehran is uploaded, this will allow a huge volume of traffic and people to be exposed to graphic content.

If I recall, Dailymotion's age gate can be bypassed by the user clicking a button to acknowledge that he/she is over 18.
