What is Skillup?
Our system marks Skillup.online as suspicious. The decision is based on a cluster of weak trust signals, not one isolated event.
Examples we frequently observe in this group: ownership data that cannot be verified, support pages with no workable contacts, reused template content, and redirects/scripts that do not match the visible site purpose. Each item alone may be explainable. Together, they increase user risk.
