Saint Seya, Kamisama Hajimemashita, InuYasha and Natsume Yuujinchou series came first to my mind

If only it didn't have the watermark?

Right, but we're talking about the popularity of text messages in the (U)States(A). And usually we don't call average Joe to someone out of the States ;)

The average Joe uses apple and thus their per-installed apps, Joe has a wrong idea about privacy friendly or secure protocols that apps like signal or matrix have. In a near future, Joe will communicate his friends between different meta apps using the signal protocol and still will consider signal a bad choice just because its marketing is weak compared to meta in the app store. The funny thing is that I've back to use whatsapp because most of my fellow US citizens use meta instead of signal or matrix or the fediverse ¯(°_o)/¯

That reminds me of a girl that used to post nsfw pics.
