How can I withdraw my paper from a fake conference? I submitted one of my research paper in a fake conference by mistake. Now I want to withdraw my paper from it, But I am facing problem in withdrawal as no email id is given on that website. The problem is that now my paper has been accepted by another conference. But according to Turnitin, my abstract is already published somewhere else. Does anyone here know how and where to report such fake conferences?
The fake conference is unlikely to co-operate – it's a fake conference operating for unscrupulous reasons. You can try, but I wouldn't expect them to play ball.

Your best chance of success is to clearly explain the situation to the organizers real conference, and hope that they understand your situation and accept your paper / talk request without problems.
