Botwatch

Botwatch is the name of the software Jagex uses to detect accounts using bots ingame. This system received a major update in September 2012 along with the release of Botany Bay. According to Mark Gerhard, Botwatch will be able to profile accounts and determine whether or not they are using botting software. Most other anti-botting measures have focused on protecting and obfuscating RuneScape ' s source code; Botwatch doesn't focus on breaking the code of the botting software but instead monitors an account's actions and determines whether or not it is human behavior. The Botwatch system will have the ability to ban players directly, making it the first automated banning system in RuneScape. This being said, Jagex is quite confident in this system and guarantees that all legitimate players will be safe. However, the Rogue Botwatch bans glitch did present an early flaw in the system.

Pre-Launch
On 18 September 2012, Jagex added preliminary bot watching code to RuneScape, and spam bots started to explode and get banned.

They can perform two animations when they get banned.
 * They gasp for breath, choke, and then fall over. (Doing the Dramatic Death Emote.)
 * They glow and start a cry emote, before a fireball burns from inside them and kills them from the inside out, finally making them explode.

Botwatch Rogue Banning Glitch
The Rogue Botwatch bans glitch was a major glitch that occurred on 27 September 2012, which resulted in the mass banning of several accounts. Around 3:30 PM Jagex time, Botwatch began removing thousands of innocent players from the game and placing unappealable permanent bans on their accounts. It would teleport the players to many locations, including White Knights Castle and Wizard's tower. If the players dropped an item, it would be instantly destroyed. Players could not trade or use the Grand Exchange. The glitch was fixed less than an hour after its discovery, and Mod Emilee issued a public apology about the issue and described its cause.

Those who were affected later had the falsely issued offences (and accompanying punishments) manually removed, and were also given 20 free spins on the Squeal of Fortune as a goodwill gesture. Some players who were affected had a number of their stats partially drained upon logging back in, to the levels where they would typically be rolled back to if they were caught macroing and given a second chance. Their base levels remained the same as before the glitch occurred, however. This could be solved by waiting for them to restore to their normal levels, banking their items and intentionally dying, or, in members worlds, by drinking a dose or two of Super restore.

The next day Mod Emilee confirmed the cause as a heuristic from the testing phase of the system which was accidentally turned on, and stated that barriers were put into place to prevent it from being turned on again. . In a Q&A session the following week, Mod MMG had stated that the number of affected accounts totaled around 40,000, and confirmed that each and every single affected account was unbanned.
