Griefing a plot using AutoSign, AutoBuild and BuildRandom.

Using AutoSign to build a wall of signs so big that it reduces everyone's FPS.¹⁾

AutoSign is a Minecraft hack that automatically writes a certain text on every sign placed by the user. The text that the user manually writes on the first sign placed after activating AutoSign determines the text that will be automatically written on every sign that is placed afterwards.

AutoSign will continue writing that text on all signs that the user places until it is turned off again. This also means that the user needs to turn AutoSign off and on again in order to change the text.

AutoSign can be used for griefing by placing loads of signs all over a building. AutoSign can also be used for spamming or advertising by writing the URL of a website, the IP of a server or other such things on a sign and then placing as many copies of that sign as possible, preferably in areas where the signs are visible to many players.

AutoSign can also be used to cause lag on a server by placing so many signs in one place that everyone who gets too close to the signs experiences FPS lag. This strategy is especially effective on large plot servers. In an experiment done by Alexander01998 and gruenwald32, they were able to reduce people's frame rate to 4 FPS on a 750 slot server.²⁾
