I wish I could try part 2 but our IT department hasn't rolled out the newer version yet.
My percentages are a bit off. Looks like I parse out slightly different data from the comments.

Nice challenge cleaning up data! Now to start playing around with the Text Mining tools for part 2...

At least I think I was able to narrow it down to challenges # 120, 122, 166, 176, 181 and 189 each containing one more empty (=No Text, just images or something) line minus the 124 original posts
16,201 records (my solution) = 16,319 + 6 - 124
