The Japanese portrayal of going viral always amuses me. Their internet is a lot smaller than ours. Heck, we probably get more traffic on a controversial chapter here on MangaDex than she is getting.
Never felt like it was a just a hook or slowly fading. Almost every chapter there's a mention of her username, Efa, or a mention about taking a picture.
100k is apparently the cutoff, which is an odd metric in my book. I've gotten that many before, and I never considered it viral. Oh well, when you're wrong, you're wrong. I concede the point.
100k is a lot of views for her little twitter blog, especially for what is literally images of an underage girl. If this was more true to life it would mean she gets banned, and if it was modern there'd be a bunch of blue checkmark guys on Elon's Hellsite talking about how she's proof that age of consent laws violate nature.
