within the game; and Forum Moderators, who are trusted players who monitor the game forums. Players who repeatedly break the rules may be temporarily or permanently banned from playing the game. There are also rules prohibiting the use of third-party software to play the game, known as "macroing" or "botting", and the sale of game items for real money through real-world trading. In an attempt to stop cheating, Jagex made direct interaction with the client difficult, established rules against the practice, and introduced random events that required player input to complete. In response to continued gold farming, Jagex issued a statement condemning real-world trading, stating that they were seizing billions of gold and banning thousands of accounts every week for cheating, and promising to increase their efforts to prevent real-world trading in the game. From October 2007 to December 2007, Jagex began releasing a series of updates to restrict unbalanced trades. The updates limited the value of items staked in duels, removed player-versus-player combat from the Wilderness, made valuable player drops invisible to other players, introduced gravestones for the items of dead players, instituted systems for assisting players with skills and sharing loot among groups of players, and established the Grand Exchange, a sharemarket-like trade system for RuneScape goods. Collectively, these changes were designed to make it extremely difficult for real-world traders to distribute gold and items to players. These features were restored on 1 February 2011 following a referendum among players in December 2010 on whether or not to do so. On 25 October 2011, Jagex released an anti-bot system code-named the 'ClusterFlutterer', as part of a game update intended to permanently prevent "reflection" bots from working. The release of this was nicknamed the "Bot Nuke", and was estimated to have banned 98% of the accounts that were using bots, eventually resulting in 7.7 million account bans. From 26 September 2012 until its removal on 20 August 2018, accounts that were banned for using bots were sent to an isolated area named "Botany Bay" to be given an ultimate punishment as decided by players. On 25 September 2013, Jagex introduced bonds to the game, in-game items that can be purchased using real currency then traded with other players or exchanged for membership, RuneCoins or additional spins on the game's Squeal of Fortune. Bonds were introduced to allow players to exchange real currency for in-game benefits legitimately, a move described
