Help!!!! GMail Unblocked All My Blocked Contacts

Well, thanks to my GMail chat settings changing at random, I have a sizeable number of blocked contacts. And all of a sudden today, ALL my blocked contacts came unblocked.

It didn’t seem like a random mistake I might have made…. I don’t even touch those settings.

My account has not been hacked. My account saw activity only from the computer I was logged on.

Why does this happen?

Rather, why does this happen only to me?

Or does it…. Has anyone else undergone the same thing? Did it recur?

Folks who designed/implemented GMail, any answers? What can I do to solve this?

And a humble request to folks reading this… pass this post along, share this post… please do something such that it comes to the notice of someone who can help.
