I got an invite to join SciPinion and I can't tell if it is a predatory journal or not. Anybody have experience with them?
The email opened with this: "Your peers have identified you as an expert in your field and you have been invited to join our highly respected scientific community. Please claim your account!" and then went and ended with: "We believe your inclusion in our community strengthens our mission and our collective goal as scientists to find the truth, we would very much appreciate your insights. Your participation in any of this may remain completely anonymous at your discretion."
