"Limitations of application in a jurisdiction include the inability to require removal of information held by companies outside the jurisdiction."
No such law for any site operating outside the US. The law also doesn't work the way you're claiming.
Not to mention the law does not in any way relate to sites having to have a way to self-delete. It's more a form of protection against information that can damage someones life if not deleted.
ie. You could request picture of yourself or posts containing your RL name and address to be deleted, but your random posts on a forum in no way ruin your anonymity outside of the site.
Good kid, some very famous websites had to pay huge penalties for bypassing and breaking the very law I was referring to. I know what I am saying, I had some law classes centered about this very topic. Nevertheless, I am sure Europe would not give a damn at all for minor and small websites, do not worry, even if Warlight is truly breaking some European Court rules.
Koala, no offense, but it doesn't sound like you understand law- warlight is not breaking it at all. If, say a newspaper posts an article claiming that you're [insert bad stuff like racist/pedofile/criminal/etc], and that is later proved incorrect you can have that article removed, including from search engines (like google). A online account is something completely different.
Additionally, as Good Kid said, that doesn't matter. Warligth is based on US, and therefore the only law they care about is American. European laws do not apply to warligth.
