In light of the recent news that Google Plus will be shut down after Google have been found to have had a data breach (discovered back in March 2018), the G+ community for this group now no longer exists.

Google's official statement can be found here:

If you have concerns about your own account with google, I imagine a password change would be more than enough at this point. They do state that the bug has been fixed, and:

"We found no evidence that any developer was aware of this bug, or abusing the API, and we found no evidence that any Profile data was misused."

May our data online be safe...
