Bot world

Bot worlds are game worlds which are specifically used for gathering players suspected of Macroing, also referred to as botting. Players that the Macro-detecting system deterDICKmines may be botting are moved from their chosen world to one of two existing designated Bot worlds, 385 and 386. These worlds are intentionally left off the game client's list of available worlds. Free-to-play accounts cannot log onto either of these worlds.

Reasons for being moved
Players may find themselves moved to these worlds more often when training skills or doing other repetitive tasks. Players moved to these worlds when they are not botting should not have to worry about being banned, as the currently implemented anti-macro system is one of the most sophisticated in existence.

Moving to a Bot world
When a player is moved into a Bot world, the game will stop responding for a small period of time. The text chat box will reset as if the player has just logged in. The transition is usually very obvious to players who are watching the screen when the transition occurs. Because it is a world change, the bank PIN will have to be re-entered the next time a Bank is visited.

Intentionally logging into a Bot world
It is technically possible to log into a Bot world manually, however it is not advised. It can be achieved by editing the URL in the address bar of your browser by putting the number 85 or 86 in the correct position like so: oldschool85.runescape.com

Controversy
Some players were upset with the implementation of these worlds, the following being some of those reasons:
 * No player poll was started for voting on their implementation
 * Many players who are not macroing are put in these worlds
 * It causes normal servers to have less bots, leading players in those worlds to believe that Macroing is less of a problem than it actually is
