Currently the Petition logic adds signers of petitions to a group whose visibility is 'Public Pages' (the default name of this group is 'Petition Contacts'). The problem with this is that, being Public, it is possible for non-signers to subscribe or unsubscribe from the list. It seems unwise to expose business internals to the public in this way.

I've supplied a patch for v4.3 (below) that makes two changes, and which suggests a third change for consideration.

• Allow the option to limit the visibility of the group 'Petition Contacts' to 'User and User Admin Only'. Currently, making the group non-Public causes an error. I doubt anyone will object to this improvement.
• Going one step further, I suggest making the group 'User and User Admin Only' if CiviCRM has to create it on the fly. This is consistent with the behaviour when creating a new group via the UI, which defaults to 'User and User Admin Only'.
• The third change to consider is to modify the third argument to CRM_Mailing_Event_BAO_Subscribe::subscribe(). Currently the $context argument allows the check "this is a public group" to be skipped when the value of $context is set to 'profile'. It seems someone else needed to skip this check when Profiles are being used. Perhaps a better scheme is a boolean argument $groupMustBePublic which defaults to TRUE. To me, that's easier to comprehend than 'profile'.

The patch for 4.3 is ...

Xav - Can you please elaborate on:
> Could you as well modify the sql init to put the group petition as private?

I have hit this issue and am in the process of creating the patch & JIRA ticket since it seems this bug was never addressed.

Ken - thanks for your patch, it fully resolved this issue.

Xavier - the group is created in the script, so there is no upgrade/install script that creates it.
