Obviously, this is a real challenge. It's a shared challenge. I would say to you that we're on the same side in this challenge; we are partners in tackling this.
We have been working very hard to sharpen the detection of these types of scams to be able to prevent them from abusing our systems. When it comes to things like public figures, for example, on YouTube, we have developed the likeness detection tool. This tool would allow a public figure to approve or deny the use of their image in content or in advertisements. This is one of the ways that we built products to be able to respond to the threat. The reality is that we're dealing with criminals who are constantly working to circumvent the protections we're putting in place.
