The little green dot on MD doesn't mean anything. Sometimes the series isn't updated as completed until the very last chapter drops. Which could be in two chapters for all we know (LHT already uploaded the next chapter).
Dude, stop trying to be That Guy. Seriously. Just stop.
I've rarely ever found the status indicator on titles here on MD to be wrong. There's only been two instances where I've had to report to the staff a correction. Once to report a series as being on hiatus, and another to let them know a series got cancelled instead of completed. (It was an incredibly brutal axe. Last chapter left off in the middle of a sentence, and then there was no more.)
And if a title that is marked as being in progress actually
has been canceled, completed, or put on hiatus? Then you can hit that little flag icon on the title page and report it for "Information to correct".
Also, since you wanna be so goddamned pedantic about it, I just checked. The last release on Comic Walker was Chapter 60... OMG! JUST AFTER CHRISTMAS DAY? LAST YEAR? OH NO IT'S AXED!!!
Seriously, that's what these guys sound like right now.
So please, don't say or do anything that enables this lack of critical thinking. People
might have a right to be idiots, but that doesn't grant any sort of special protection.
