Hackers, skids, and hatters pose threats to Minecraft servers. Hackers use cheating techniques to gain advantages over other players and are difficult to permanently ban. Skids falsely claim hacking abilities and may try to take servers offline through DDoS attacks or recruit other hackers. Hatters are more skilled hackers who could potentially discover personal information to harass server owners. Minecraft originally only required logging into private servers but now offers paid Realms servers directly through Mojang to prevent hacking. The game has expanded from PC to consoles and mobile, opening new markets and allowing cross-platform play through a single version with the "Better Together" update.
