Brimstone

Brimstone is a form of coal that actively harms the posters who view it due to how incredibly low-quality it is. Brimstone is often considered to be even worse than dust, with prolonged viewing posing a serious risk to the viewer's body and soul. The evil qualities of these sinister posts commonly lead to derailment of otherwise gemmy threads.

Many images that meet the brimstone criteria can be traced back to Twitter where users who have little to no knowledge about soyjaks attempt to make 'jaks of their own.

As noted by the Holy Soyble in Nate 18:25: "It is easier for a plus-sized black trans queen to go through the eye of a needle than for a poster of brimstone to enter the kingdom of Soot" Which implies that posters of brimstone (and potentially those who enjoy it) will burn in Hell for eternity.
