Brimstone (sometimes Gravestone/Grimstone or Niggerstone) is a form of coal from H E double hockey sticks 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. Some types of brimstone rapidly grow like a cancer before dying out just as quickly. Overall, brimstone is a very macabre quality of post, and should generally be avoided. Most people who post brimstone WILL burn.
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.
Types of Brimstone
Silesian brimstone consists mostly of sulfur but with some impurities. As a result, it is not as strong as the other types but can still coal up the log in high enough quantities. A notable example of Silesian brimstone is the Polish BBC spammer.
Bhutanese brimstone is around 99.89% pure. It is much stronger than the Silesian type and small doses of it can turn the entire catalog into dust. It is recommended that you avoid exposure to Bhutanese brimstone as it has a high chance of causing nigger AIDS.
Congolese brimstone is 100% pure elemental sulfur from the deepest, darkest pits of Niggerhell. After its discovery, Belgian authorities sealed off all brimstone mines in the Congo and erased any information about it that they could get their hands on. As a result, not much is known about Congolese brimstone, but soyentists theorize that it could completely destroy the Sharty. It is speculated that Poopson is made out of Congolese brimstone.
