question: how do you check for new titles?
1. i check mangaupdates because mangadex didn't get their shit together 2 years in yet
2. i check the "new titles" at the bottom of the main page that get bumped with way more then the threshold if i ever dare to sleep in the weekends
3. i check the new chapter listing, which is coherent and full
for me its 3.
next question:
how do you know a chpater belongs to a new title?
1. i open every single chapter because i have nothing better to do in my life
2. i open every chapter of a manga that has less than 10 chapters
3. i open chapters of mangas that has less than 10 chapters and i don't personally remember encountering
ofc its 3
last question
how do you know a chapter of a manga that you recognize by title and cover is in fact an entirly new manga?
answer: because the NEW manga will come with an altered name to difriant from the OLD one.
the new manga should be renamed with (post serialization), not the existing manga renamed to (pre-serialization).
this is not a personal problem, it can happen to anyone. the blame is on mangadex for still not having a new title page, but the uploaders are not free from it when they choose to change names of exsiting titles instead of the new ones.
