In SharePoint 2013 sharing content or a site generates an email to the user which contains a link to the content and information. It also contains an option to follow the content or site...is there a way to remove this from those emails?
This technically is possible, however you would be editing the resource files installed by SharePoint. Doing this is NOT supported by Microsoft, could break things, and could get overwritten during future updates.
If you are feeling adventurous in a test environment, however, the location of the resource files is here:
C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\15\Resources.
