Peer review by Hindawi is very week. Hindawi has a lot of case report journals with a lot of poor quality and plagiarized materials.
In Hindawi’s ISRN journals, peer review is ridiculous. Each manuscript is sent up to 5 reviewers. Based on majority, the decision is made. If 3 out of 5 reviewers give positive feedback, they publish. This is stupid peer review policy. The acceptance or rejection should be done by the editor (not Hindawi’s staff) based on strength of comments made by the reviewers rather than number of reviewers giving positive feedback.
