Just in case somebody needs to read this:
Recently, different translator groups have been sending out reminders because there are people who are posting screenshots of mangas/webtoons and then tagging the artist, sometimes even messaging them (usually meant with good intentions, like praise or adoration). A few artists have actually seen them, and since those works don’t have official eng releases, it was a really big tip off.
So yeah ... don’t do it. But especially don’t tag. I’ve seen a few cases of artists threatening to drop a series, translators hit with cease and desist letters and then having to drop the series. Not sure if legal trouble has gone beyond that before. But either way, no post or tweet is worth any of that.
