I think 4chan or any chans use some sort of image posting app. I think you can anonymously post anything. I even traced the source of Qanon on these boards. a guy (made a vid on it) having fun with it and everyone goes bonkers with imaginations. Some false pizzagate hoax. Even trump believes it cause some guy made up the root cause of "Q". You can pick a board and make up sh*t and pick an alphabet, "X" and watch Magas go bonkers and wait for a dead person show up. You can make up Biden is an actor. Magas are still waiting.
