Some of my colleagues and I got offers from employees of some reputed journal (not from journal itself), to publish our research paper for free, if:
- We include their name as co-author
- We use 60%+ citation of their journal (Doesn't it add up to IF??)
In return:
- It will be published completely free
- They will give us discount of some sort for next publication
Is it may be some kind of scam?
