Error since installing Easy Blog and Easy Social

Since we installed Easy Blog and Easy Social we have had an ongoing issue This error appears on our home page and through the site "JUser: :_load: Unable to load user with ID: 96272" The user ID does not exist and if we give a user this id it goes away but comes back. The other thing we have noticed is that one of my users is being replicated over and over in the user database. Go into database and delete all the user continues to replicate with thousands of times a day. I have looked everywhere but cannot figure this out. Help Please and thank you in advance.
