Looking for mangas chapter discussions with large amount of comments.

Here are two examples that I have found.
They currently have 309 and 292 comments respectively. Please be respectful of any discussion going on and do no comment that this forum post brought you there.

You can go to the chapter discussions subforum and sort the threads by reply count:

300 comments are rookie numbers

That winning childhood friend one seems to have a lot of what is no doubt highly civil discussion across multiple chapters, and I believe has the most commented chapter in v5 (unfortunately there's no good way to filter on v3 vs v5, or date of creation). And let us not forget that Bisque Doll had some record-breaking numbers in the final arc.

Never thought I would see the day of a manga having over 100 comments per chapter, not since V3 at least.
