Pixel Worlds should feature Agents, which monitor players at Pixel Worlds. Agents are normal, trusted players, which prevent bullying, scamming and cheating in the game.
Agents can activate Undercover Mode and give warnings to players. Agents have their own agent chat, which also includes Moderators, admins, etc. Agents can report problematic players to the agent chat, and Moderators can investigate those issues. This will ensure that every problem in Pixel Worlds can be resolved.
Agents can be identified by the color of their name. It eliminates the possibility of a possible scam.
If you like this idea, I would love to be ready as an agent!
