This is a screenshot of the content of the Journal of Digital Economy. Do you notice anything suspicious or problematic in it?

The papers published in this issue of the Journal of Digital Economy do not correspond to the journal's title. For example, four out of five papers in the screenshot are associated with medicine rather than the digital economy.
This is one of the characteristics of hijacked journals, which turn multidisciplinary to maximize the number of accepted papers. The Journal of Digital Economy has been hijacked, and the cloned version shown in the screenshot publishes papers of all types and topics.

Hijacked journals are the illegitimate clones of authentic journals. Check the list of hijacked journals using the Retraction Watch Hijacked Journal Checker.
