// @description This is a modified version of the Reddit Overwrite Script located here: https://greasyfork.org/scripts/10380-reddit-overwrite/code/Reddit%20Overwrite.user.js 
//The original really upsets moderators because it leaves behind a link to the script. This version simply leaves behind a blank post. I swapped out all the text for a simple "" in line 98. If this breaks in the future, you fix it. I am not a programmer, coder or ...what? Scripter? This is my shade tree fix for something I did that upset quite a few mods and got me banned from r/dataisbeautiful. Fucking read the fine print before running something guys. And be nice to the Mods, half of them don't know who their parents are, and the other half are outcasts kind of like poor Harry Potter, but with no owls and no magic. They mean well and do their best for you despite you guys never ONCE sending them a Christmas Card or even saying "thank you."
