Agreed... but I also wonder why this is? I undertsand this is out of Webtoon control, but even looking at it from the google perspective it seems silly.
Wouldn't it make more sense to let us mark/tag our content and then cater the ads to that. What I mean to say is, I can understand how some companies want their "wholesome" ads to be on controversy-free content, but there are definitely people who can't possibly care - I'm thinking a lot of Video game ads, or ads where "sex sells" wouldn't those companies prefer to target the audience that reads mature content?
I feel like it's a totally missed opportunities for marketing.. but maybe it's too hard to implement.
