Canvas 6 >

The 5th canvas saw the joining together of several factions to keep an orderly central region of the canvas; Blue Lattice, RGB Lattice, Cell Lattice, and the Ukrainian faction which ended up building a fort.
It also saw an attempt at building a Confederate Battle Flag - which was quickly squashed and drawn over by the LGBT lattice and others.

The canvas also saw the exposure of bots, made more clear by the reduced number of users on the canvas.

An ancom/ancap/an* flag was, as is tradition, a target of change. As was the world map, with different nationalities having different world views and expressing them onto the map. These resulted in some of the brightest regions in the heat map.

The server logs for the 5h canvas were publicly released, with usernames removed. See the anayses section for more information.

Untouched pixels

Pixels that were never placed on (also referred to as virgin pixels), depicted in white.

Canvas 5 - untouched pixels

Pixel age

Age of pixels as a brightness map. Darker pixels were placed longer ago.

Heat map

Depicting activity on the canvas as a heat map - the brighter a pixel's color, the more often it was placed on.

Banned pixels Layers

These were pixels from users that were reverted, typically after a ban (bot, multi-user, disallowed content, etc.) for the first time for that pixel, presented in their pre-ban pixel color. For clarity, the background color in these images is presented as a hot pink.

Canvas 5 banned pixels - layer 1

In some of the locations where people were banned, were slow to clue in and continued their botting/multi-accounting, so they got another round of bans, shown in this second layer.

This continued for a third time:

And, ultimately, for a 9th time for a highly contested area, the world map:
