Dear Himal Thapa If you mean “Global Scientific Journals" https://www.globalscientificjournal.com there are numerous red flags:
-Use of a prominently mentioned impact factor is misleading since it is an example of a so-called misleading metric CiteFactor (see also: https://beallslist.net/misleading-metrics/ )
-The pointless and not working logo’s/links to journals are made-up titles with journal cover pages stolen from books. See for example https://encrypted-tbn2.gstatic.com/images?q=tbn:ANd9GcTtOAI4oj89LCW4lmF2xUSBSFlEs5_TWOa2Ii1-7-z7TzSXcg1n and https://www.scribd.com/document/432198540/10-Physics-2020
-The ISSN 2320-9186 is fake or at best seems to belong to another vague journal
-Contact info is basically absent
-For the papers I checked their claim that the papers are indexed in Google Scholar is not true
