"The facebook owner is himself of Jewish descent. He may not care because it's business for him."

It will be of little importance in the future if the website owner(s) don't care or appear not to care.

There are many groups who by direct action will make them take notice. Pro-Publica is a group of investigative journalists who drew attention to the Facebook problem. There are other groups including lawyers who are challenging laws on jurisdiction for hate speech and racism. One loophole is where the server is located, but I've been told that this may not be relevant any more.

In Germany, for example, Holocaust denial is a crime and tourists and others who do nazi salutes can and will be arrested.
