It’s important to remain vigilant against deceptive websites:

July 18, 2025

Due to unavoidable circumstances, journal publications experienced a temporary suspension, during which misleading domains such as https://combinatorialpress.com/um/ (see in this all journals are clone) and www.combinatorialmath.com appeared. While the latter remained dormant, the former, under the guise of Utilitas Mathematica, disseminated unverified content that does not uphold the true legacy of Utilitas Mathematica.
