• Malvertising: Many "unblocked" aggregator sites rely on third-party ad networks that do not vet advertisers. In 2021, there was a noted increase in "drive-by downloads" and phishing attempts masquerading as "Play Now" buttons on these sites.
• Bandwidth Consumption: While individual IO games are lightweight, hundreds of students accessing multiplayer servers simultaneously could strain school network bandwidth, affecting legitimate educational streaming and testing.
• Proxies and VPNs: The methods used to bypass firewalls to play these games (such as using browser-based VPN extensions) often opened security holes, potentially exposing student data or allowing malware to bypass the school's perimeter defenses.
