Yes, using cheats or hacks can definitely lead to an immediate ban in most online games. Developers take cheating very seriously as it undermines the integrity of the game and creates an unfair environment for other players. Many games have strict policies in place, employing anti-cheat systems that automatically detect and ban players who are using unauthorized software. The consequences can be severe, often resulting in permanent bans without the possibility of appeal. This is true even in more casual games, such as unblocked slope, where cheating disrupts the experience for others. It's always best to play fairly to enjoy the game fully!
