I have heard that many predatory/fake groups organize international conferences and Magnus is one of them if anyone has previous experience of it. please share.
It depends on your expectations. If you consider it legit when it actually takes place, then I guess it is. If you expect a high-quality meeting with interesting experts and fellow researchers active in the same field, then I am afraid you will be disappointed. The following red flags can be found:
-On a site about predatory conferences https://www.evscienceconsultant.com/blog/predatory-meetings-and-how-to-avoid-them (they are mentioned as Magnus Group)
-See also the reply of Baruh Polis here on RG https://www.researchgate.net/post/Hi-everyone-Please-anybody-can-tell-me-about-Magnus-Corpus-conference-Is-it-a-genuine-or-fake-conference-organizer
-If you Google the contact info 150 South Wacker Drive #2400 Chicago, IL 60606, USA mentioned on their homepage https://www.magnusgroup.org it appears to be a virtual address (in other words why hide your true origin?)
-I think that some of their collaborators (sponsors) are fake, for example this “+ Medex” has no online presence…
