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.
This is a horrible situation for you. Until this moment, I never heard of "fake conferences". I just read about them, and the source I was just reading said, and I'm paraphrasing, there is very little difference between fake and legitimate conferences because they are both based on status-enhancement and profit-making rather than the spreading/seeking of knowledge. Unbelievable.
I would report it to your administration and discuss it with them to find out if there's any official action that can be taken. If there isn't any recourse, then I think you have found yourself a MAJOR career opportunity. Set up a business that clarifies which conferences are fake and which are legitimate. Sort of like an "Angie's List" of conferences.
