I have received an unsolicited request to write a chapter for a book relevant to my research. I have searched the current editors and they are actual people but not very well known in the field. On their website they show various logos, including web of science.
They do not seem to ask any money, but I see that sometimes go Intechopen was listed in the predatory editors. Is it still the case? Or is it because it is an open access editor that big publishers are trying to work against it?
