Badmathematics: Your comments are unwelcome shit and will be ignored.

Dear editor,

I am in the possession of a proof that the complexity classes P and NP coincide exactly. I write to your illustrious and prestigious ~~subreddit~~ journal with the hope that you might publish my manuscript detailing the proof. I have included, for your consideration, a high quality printed draft of the manuscript, along with sketches of the desired figures.

I look forward to hearing from you.

Yours truly, Karl Theodor Vahlen
