Dante, Botfag, the squad, and Plague are the four biggest cancers we've ever had because they're the only ones that have left permanent impacts on the entire culture of the thread
Dante caused threads to overflow with obsessed trolls like Scetic and also fellow retards like Poopcat, pushing them further away from drawing and more towards unrelated lolcow drama and autism
Botfag brought all the worst requestniggers over from other boards to bitch about him so now requestnigger drama has basically become the center of drawthreads
The squad normalized spam and shitposting to the point where even some drawfags like Nyan spam pasta now and reference forced /qa/ and discord memes like "new 'toss" or Sgt. Braphog
And Plague made it so now when all this shit is happening, drawfags have the option to run away and hide on Discord and in drawpiles so that threads have no hope of ever improving due to utter lack of drawfags
These people are the 4 horsemen of the drawpocalypse, and they can be blamed for pretty much all the problems that threads face today and will likely continue to face for potentially years to come.
