The following video: https://www.youtube.com/watch?v=q_otSO1Ab9w is a from a series of videos from the University of Florida.At the end of the video, there were the following links on the screen:

Since, I could not click on the screen, I decided to type each link in the comments. But, later on my comments disappeared. So, I have once again posted a single comment on the video saying "I'm writing the above links here so that we can click them. Please do not remove this comment.", followed by the above links. I cannot understand why my previous comments were removed.
