Terrible policy and *easily* bypassed
1) Blizzard Entertainment's World of Warcraft/the Battle.NET account system requires the registration of a name and address. However, there is absolutely no reason to use your real name or address! Blizzard do not authenticate in any way shape or form against this name - not even if you use a credit card for payment.
2) WoW allows the use of pre-paid game cards. These are anonymous cards available from any game shop or can even be bought online, e.g. from Amazon.co.uk. They are actually a very efficient method of payment and are often significantly cheaper than paying directly by credit card!
3) Even if Blizzard were now to go to ridiculous lengths with their new system and ban game cards, there are easily available pre-paid/virtual credit cards from Visa and others which once you register with real details allow the creation of any names on the virtual account and card.
In addition, people seem to ignore four vital aspects to this new policy:
a) at least Facebook and other sites which use private information are not easily publically indexable or offer options to prevent such access without preventing access to the sites services,
b) once information is out on the open Internet, it is persistent. This is kind of the whole point of the Internet,
c) privacy is not just for the moment, it is for life. If you give up your right to privacy at any point in this day and age, you have given it up for the future. This may have serious repercussions down the line for any given individual,
d) if a company has this much contempt for privacy and is prepared to experiment directly with people's lives on a grand scale, there is no reason why they should stop here. Those talking about this being restricted only to forum postings are a little naive. This has already been demonstrated by the existing easy exploits to obtain Real IDs by perfect strangers. Due care and attention goes out of the window when personal information is of so little value.
In short, this appalling policy which makes Facebook look like a privacy advocate in comparison, can be easily bypassed by all members of the gaming community if they so wished, and demonstrates a clear disregard for the concept of privacy.
Blizzard now want you to not only risk your precious time but also your even more precious real life information for this allegedly addictive game. At the end of the day, its just that: a game. No matter how blurry this distinction may seem to some of the WoW community, including Blizzard Entertainment, it is never worth risking your life for a game!
