2011 Bot-Nuke/ClusterFlutterer

On 25 October 2011 at 2:37 PM GMT, an update code-named ClusterFlutterer, AKA "Bot Nuking Day" took effect to prevent reflection and injection bots from working again. Jagex believes that this consists of 98% of all bots seen in the game. Also, upon revealing ClusterFlutterer, Jagex stated that over 1.5 million bots had been recently banned. Due to the complex nature of the game update, the update was finished 2 hours and 37 minutes after the countdown timer reached 0, resulting in the game being offline for approximately 1 hour and 7 minutes while Jagex updated and tested their systems. After it was finally finished, populations in almost every world was excessily lower (in some cases, some f2p worlds had 100 or less players)

To celebrate, Jagex decided to do the following: * indicates that the D&D will be reset on the day if already done for the week. Players can spy on all penguins on the day they reset (Wednesday), and then again on Thursday, which will give them double points. This will give them a maximum potential of 48 points in 2 days (16 on Wednesday and 32 on Thursday due to double points). This is two points below the maximum cap of 50.
 * Tuesday: Triple experience for training Slayer.
 * Wednesday: Triple tickets from Castle Wars.
 * Thursday: Bonus experience from certain Distractions and Diversions.
 * Penguin Hide & Seek: double points*
 * Evil Tree: triple experience
 * Shooting Star: triple experience and increased reward
 * Familiarisation: receive both charm and ingredients reward*
 * Friday: Triple zeal from Soul Wars

No in-game multiplier or bonus xp icon was used to indicate the triple Slayer xp.
