What Is 8ku.us?
8ku.us is a website that claims to generate free Robux for players of Roblox, one of the world’s most popular online gaming platforms. Robux is the virtual currency used to purchase avatar items, game passes, and premium features.
The site presents itself as a “Robux generator,” allowing users to select an amount of Robux and enter their username. It then claims to connect to Roblox servers and transfer the currency.
However, there is no evidence that the site actually delivers any Robux.
