So Google+ is a big flop, people don’t like it and don’t want to use it.
What does Google do? Forces you.
Many people are reporting that their most frequent chat buddies on Google Talk have been blocked automatically by Google, with the only available solution to be joining Google+ and unblocking them there.
Google are aware of the “problem” and claim it is a bug, however all the other (previously available) workarounds like using the stand-alone client to unblock have been disabled after being reported working to Google in this thread.
More reports and details here.
It appears that someone became quite desperate there in Google+ team, and after all the other strategies failed decided to just force people in to boost membership. And of course, you cannot become a member without providing a great deal of personal information, starting with your name.
Google, back off.
