Julian Assange, the Australian founder of WikiLeaks, is getting some powerful help in his time of trouble.  Some Swedish women are accusing Assange of sexual misconduct, and a number of his financial backers, under pressure from America, have either pulled their funding or refused to have their servers used to carry the site's hosting.  Assange has turned himself in to London police while he fights extradition to Sweden, but his supporters fight on.  A group of so-called "hacktivists", operating under the umbrella name "Operation Payback", have launched denial of service attacks against MasterCard and a number of entities that have been troubling Assange lately.  MasterCard's Web site was down almost all day yesterday and is still sluggish today.  The Swiss group that handles Assange's bank account has also come under attack, and Twitter, accused of censoring messages relating to WikiLeaks, has been warned they are next on the list.  PayPal, which handles some of WikiLeaks' funding, is on the potential list as well.  Meanwhile, the Facebook page for WikiLeaks has passed one million fans.
