A founder sharing a login is after a site redesign and needs a webtoons site. Search puts an ad, a copied layout, and the real host in the same list. The title on the page is not enough to tell them apart.
Webtoon reader apps and unofficial mirrors share the same series titles. Open the publisher from the webtoon category, then check the series title on screen.
Use one reviewed category page instead of a folder of old URLs. 주소메뉴 웹툰 is the JusoMenu webtoons list. Open it, pick the name you meant, and read the address bar before you type anything.
Do not install an extra reader to unlock a free chapter. If the name on the next screen is a different brand, close the tab and return to the same category.
Bookmark that webtoons category, not the article you found after a site redesign. Section paths move. The category page is the page you can reopen next time without guessing a host.
Before the next webtoons login or payment, a founder sharing a login should open the category, match the host, and stop if the screen name differs.
