Higher Logic Online Communities users receive an informational “following” email when other
users contribute to message threads that they’ve initiated or to which they’ve responded, to
inform them of new discussion on the message thread. Members in some Online Communities
received these “following” emails for message threads to which they had not contributed,
including for communities they were not members of.
Root Cause
We incorrectly updated SQL query criteria used to determine recipients of following emails.
The altered criteria were used to exclude a subset of users based on their community email
subscription settings. The update to the SQL criteria caused that subset of users to be
included rather than excluded, which caused certain members to receive additional emails.
