According to /u/Spez, Reddit CEO, the reports of messages edited without any user consent or knowledge are correct as he admits to have done it so himself:
Hey Everyone,
Yep. I messed with the "fuck u/spez" comments, replacing "spez" with r/the_donald mods for about an hour. It's been a long week here trying to unwind the r/pizzagate stuff. As much as we try to maintain a good relationship with you all, it does get old getting called a pedophile constantly. As the CEO, I shouldn't play such games, and it's all fixed now. Our community team is pretty pissed at me, so I most assuredly won't do this again.
Fuck u/spez.
The edits were made in a thread linked from the Washington Post which described the recent ban of the /r/pizzagate subreddit which tried to uncover child-molesters and recently moved to voat.co.

Oh, right, that was Obi Wan-Kenoba-Whiteboy. Still, my message remains the same. Stand strong in the face of the Black man and your strength becomes that of the Black man.
When I left you I was but the house-nigga. [youtube.com] Now, I am da massa.

“Darth Ethanol, Massa of Evil” would be a great name for a satirical superhero. His arch–enemies could be the Army of Special Schnowflaykes, whose greatest weakness would be their tendency to become blinded by their own tears when offended.
