I don't think that any of the celebrities will be stupid enough to provide real information (such as name, DOB, sexual preference.etc) on their AdultFriendFinder profiles. If anyone is that stupid (there will always be a few, with sub-60 IQ), then this will be the next "fappening" blow to the celebrities.
That would be the continuation of the Iphone hack
In recent news we discovered X celebrities also used AdultFriendfinder
Well just a matter of time there might be a few in there or a bunch of fake profiles that used a celeb photo / name for their profile account.
That said if the hacker was the same one that did the Iphone hack they have the data to compile fingerprints that can be used to determine what celebrities frequented both sites
If a malicious party obtained identifiable access logs for just one of the websites that know your name, and view logs for just one of the adult websites you’ve visited, it could infer with very high probability - beyond plausible deniability - a list of porn you've viewed. At any time, somebody could post a website that allows you to search anybody by email or facebook username and view their porn browsing history. All that's needed are two nominal data breaches and an enterprising teenager that wants to create havoc.
For the curious minds here wondering how it would be proven

Not all celebrities heck very few users in general address Unique ID footprints so its possible if there is two sets to remove/reduce plausible deniability.
