Youtube Comments Being Hacked

Just now i was surfing youtube as usually, and i watch back the video that i posted in my last post, i found that there is some problem in comment column, that is it can't shows the comments that leave by others.



I wonder is it my own problem or what, so i try to use Google Chrome to surf this post, but end up with the same results. Then i try to surf other posts , some is just normal, and some shows " IF_HTML_FUNCTION? " , follows by some words.

I try to watch the Youtube most popular/viewed video in the day and it has the same problem.



It seems that the comment fields have been hacked by some kinds of html script.
