I sent an email to Truthout.org, asking if they wouldnt accept bitcoin so I could make an anonymous donation. I got this reply:
Thank you for supporting Truthout! Per your email, we do not currently have a bitcoin account but this is something we will look in to. If you would still like to make an anonymous donation, please consider calling in to us, 213-489-1971, and I can process a donation from you with just your credit card information so the donation can be completely anonymous.
Thanks again for your support. We truly appreciate you!
Completely anonymous credit card transactions
