Hi there,
May i know if that user still can access your Easysocial page or not ? If cannot access, you can disabled this settings
http://take.ms/El01P and they will not be listed on your site and this user will not be able to access Easysocial anymore.
If yes, you wanted them to be able to access your Easysocial and etc, you can disable this setting here

Please give it a check and see how it goes.
