Dear Azzedine Fercha Your observation resembles issues as discussed here on RG https://www.researchgate.net/post/Why_this_email_address_sakaijuro45gmailcom_has_recently_been_associated_with_numerous_scientific_journals

Indeed, the journal “Tobacco Science and Technology” is according to https://retractionwatch.com/the-retraction-watch-hijacked-journal-checker/ an already identified example of a hijacked journal. The website of the fake version of the journal is https://www.tobst-cn.com

The original website used to be http://www.tobst.cn/ and is (still) Scopus indexed https://www.scopus.com/sourceid/21100239247 It is an exclusively Chinese journal https://portal.issn.org/resource/ISSN/1002-0861 see also https://www.ncbi.nlm.nih.gov/nlmcatalog?term=1002-0861%5BISSN%5D

I found (limited info about) one example of a genuine paper of the legit journal

Structure and composition difference of arbuscular mycorrhizal fungi community in roots of flue-cured tobacco varieties

So, indeed the website https://www.tobst-cn.com/ is definitely the hijacked version.

Looking at the use of the mail account you mentioned it renders a long list of hijacked versions (or fake websites):

Looking at SCImago https://www.scimagojr.com/journalsearch.php?q=5300152224&tip=sid there is no mentioning of the homepage and together with the comments I think the website https://www.worldsresearchassociation.com/ is either fake or hijacked.

So, you stumbled on a pool of deception and it is clear that all these ‘journals’ are created by one and the same person or group of people.

All we can do is sending out this warning.

Best regards.

PS. In some cases no original website was found and are not yet identified as hijacked versions but the resemblances between all these sites (proven and not yet proven hijacked) is enough to say: hijacked and avoid.

Update: As indicated in the menatime most of the titles are now included here https://retractionwatch.com/the-retraction-watch-hijacked-journal-checker/
