A French advocacy group has agreed to handle credit-card contributions to WikiLeaks, giving the nonprofit anti-secrecy organization a possible end run around a ban by major card companies on processing its donations, according to Forbes and CNNMoney.

The Fund for the Defense of Net Neutrality will accept donations to WikiLeaks via the French payment system Carte Bleue. In a statement Wednesday, WikiLeaks said Visa and MasterCard—which have blocked payments to the whistle-blower site since it published a trove of State Department cables in late 2010—are contractually obligated to allow transactions through Carte Bleue.

WikiLeaks has blamed the payment blockade for the perilous state of its finances. The organization had about $120,000 on hand at the end of June, compared to $980,000 in December 2010.

“WikiLeaks advises all global supporters to make use of this avenue immediately before Visa/MasterCard attempts to shut it down,” the group said. Visa and MasterCard did not immediately respond to Forbes’s and CNNMoney’s requests for comment.
