Twitter did eventually get its shit together and lift the API limits on NERV’s accounts, but people on JP Twitter were furious, and “Elon” in Japanese (イーロン) was trending, with people basically cussing him out for effing up Twitter by limiting NERV and getting rid of the chronological timeline. Folks were also upset at all the “reply zombies” (blue check bot accounts) commenting complete garbage like “nice” and “happy new year” in posts about the earthquake.
As for misinformation, the evening of the quake “人工地震” (manmade earthquake) was trending on Twitter, and NHK news yesterday actually had a segment on last night explaining that no, the quake was not manmade, and that misinformation was being spread on Twitter.
