Short of asking the original posters about their dot entries, I don't think we're going to find out.
I can hazard one guess.
If you post a comment and then decide you don't want it to stand, you have two options.
You can either delete the posting - in which case it will simply disappear - or edit it down to zero - in which case the posting will still show but no longer contain the material you have edited out. However, one rule of the site software is not to allow a posting with nothing in it, so I guess the only way to save the revised posting would be to add something that is not a blank space. That may explain the dot? Although any other single character would also work.
