shabazmoqsud your profile posts there is scrolling no load more
Strange -- I do get the Load More prompt when I look at my own posts.
I saw no problems when I looked at a couple of other random users. But then I tried some staff members:
All of those stop after between 5 and 20 posts. So I'm guessing there's something that staff members do more often than others (perhaps, sending PMs), which is terminating the posts display.
