OK Rick
I turned off the facebook icon and see if that stops the flooding and let you know if that worked. Not sure why just the icon turned on would cause them to flood the server with requests
Right before I turned it off the who's online showed at least 25 facebook hits concurrently within a few minutes
I updated to V 7.5.6 over 24 hours ago so you'd think they would have cached the 2 posts I myself set to like
