FYI - don't message /r/food. I had a brief browse and saw absolutely no posts whatsoever about the blackout. Very much business as usual as if nothing happened. So I messaged them, their response was "Thank you for your unsolicited message shitting on our protest." and banned me lol. So leave them to it. I was pretty careful to word my message maturely (the first paragraph said 'I hope I’m not coming off as unreasonable, but I do think it’s vitally important for this protest to continue for it to have any real impact.'), but I guess some just really can't live without their Reddit addiction.
