Let's leave behind the Chinese Whispers or Serious Source argument though, shall we, and instead look at the security implications of Johnny Depp not being dead. As strange as that might sound, it is very serious indeed.
We've seen in the past how the death of a celebrity can be hijacked by scammers and spammers and bad guys alike. Most recently and most infamously in the case of Michael Jackson.
Just because Depp is very much still alive does not mean that the same malware merchants will not bother coming out to play, they will. In fact, the being alive aspect of the story makes it even more appealing.
After all, the search engines are currently buzzing with folk desperately trying to find out the truth. Leaving the bad guys ample opportunity to attempt search engine poisoning scams, and the spammers to get going with their malicious link campaigns.
Twitter will be ripe for the link picking, so I suggest you are very careful indeed about which links you follow with regards to the Johnny Depp story over the next few days.
