The Undercity is a crime game, and the crime stays in the game. Players from Brazil, the United States and everywhere else share the same streets and the same chat. These rules keep the city a place people want to come back to. They apply everywhere you can write: the global chat, the gang chat, whispers, your street name, and your gang's name and tag.
Trash talk about the game is part of it: brag about a raid, taunt a rival gang, swear revenge. What is not allowed is going after the person: insults, humiliation, following someone around to provoke them, or ganging up on one player in the chat.
No racism, slurs, or attacks on anyone for their nationality, ethnicity, religion, gender, sexual orientation or disability. That includes Brazilians against Americans and Americans against Brazilians: both are welcome here. No Nazi or extremist symbols, names or praise.
Nothing sexual in the chat, in names or in whispers, and no sexual harassment. Anything sexual involving minors ends in a permanent ban and is reported to the authorities.
No threats of real harm, not even as a joke. Never share anyone's personal information (real name, address, phone number, photos, social media), and that includes your own. Don't encourage anyone to hurt themselves.
No flooding, repeating the same message, walls of emoji or capitals, advertising, or links to other games, servers or groups. Don't beg other players for money or items.
Selling in-game cash, items, Gold or accounts for real money is not allowed, and neither is buying them. No fraud: don't promise a trade you won't keep, and don't trick anyone into handing over their account. Trades between players are at your own risk; we don't undo them.
Don't pose as a moderator, as The Undercity, or as another player. Nobody from the staff will ever ask for your password, your e-mail code, your Gold or your cash.
Street names, gang names and gang tags follow the same rules. The moderators change an offensive name, and the account can be sanctioned.
No cheating, bots, scripts or automation, and no abusing bugs: report them with the bug button in the top bar instead. Extra accounts used to send money or items to your main account, to farm invites, or to attack on its behalf count as cheating.
Write in the language you like: the chat translates messages on its own. Don't attack anyone for the language they write in.
If you think the moderators got it wrong, you can appeal once per sanction, from the page the game shows you (the e-mail links to it). A moderator reads it and either lifts the sanction or answers you there. The e-mail address does not take replies.
Tap ⋯ on any chat message to Report it, or Block the player to stop seeing their messages. A report goes straight to the moderators' queue. You can report a gang message or a whisper too: the report is what lets a moderator see it.
