Yes. In fact, we've been almost continually investigating Facebook since about 2009. There are clear rules. We have intervened time and time again to check as to whether or not Facebook was following these rules. The first time they weren't. In subsequent investigations, it seems they had a higher level of compliance.
The problem with social media companies is generally their lack of transparency with regulatory authorities. It takes a very skilful investigation, with a lot of experts, particularly in information technology, in order to find out really what they're doing.
