While some users employed the tool for malicious purposes, others used it to expose vulnerabilities in Blooket's system, highlighting the need for better security measures.

Today, Blooket is more secure. While some "flooder" scripts still circulate, they rarely work without session tokens or proxy rotation. The 2021 flooders are of early edtech API vulnerabilities.

The Blooket Flooder 2021 operates by using scripts to simulate multiple player connections to a Blooket game. This can be done by generating fake player accounts, spoofing IP addresses, or exploiting weaknesses in the platform's authentication protocols. Once activated, the flooder can cause significant disruptions to the learning experience, including:

Blooket added "hidden" checks to ensure that a real human was behind the screen.

Blooket frequently updates its security to bypass these "flooders," meaning many 2021-era scripts are now obsolete and non-functional.
