I don't know who started it and when but the placeholder here in mangago literally means just that - something to hold the line in place of future or upcoming ch. It's because sometimes mangago bots rips chapters from other sites with bad translations and uploads it here, so uploaders/scanlation teams uploads a placeholder or a dummy chapter to trick mgg and prevent bots from uploading. Then when it's time to upload the official chapter, the scanlation teams can just take down the placeholder and replace it with the real one (with better translation). Hopefully this helps, I'm not really good at explaining
Idk bots can do that ?? i thought maybe the readers upload those chapter
So can we watch new chapters after these damn placeholder
Who started the trend huh its so annoying i got notifications just to see there is no new chapter
