I know Webtoon Editors go through Canvas to find the hidden gems but I also heard some Originals started because authors were pitching their ideas in conventions (I don't know if it's 100% accurate tho', they may have noticed random comics and liked it xD).
My question is, do they take submissions through email like in the old fashion way, basically, you send a PDF pitching your comic project?
Is it okay to do it or they'll probably instant-blacklist you because you were annoying for even trying
?
