Notes:

Sauce: https://www.reddit.com/r/GradeAUnderA/comments/4jecfs/here_is_one_page_of_grades_comments_that_he/

I'm glad that the people from GradeA subreddit screenshot this and put them all together.
In that case there'll be more evidence to expose GradeA later on.
But the source says this is page one of deleted GradeA comments.
So we might have to wait for the second page to pop up in subreddit.
