I just noticed that in the forum if a person 'likes' a comment more than one time it allows each click to be counted multiple times and displays multiple avatars.
As you can see in the attached image there are two images from one user and three images from another user. It states there are 6 likes but there should only be three likes and only one image of each person liking the comment.
Here is the url:
click on the red heard at the bottom of the comment to see the duplicate counts and images.
As well you can note that some of the replies/comments are also displaying multiple times.
