Violated by technology

I recently found a way I have been violated on Facebook. Take note if you were a user before 2010! Your private inbox messages are now visible for all to see, from 2010 and earlier! This could get VERY awkward, very quickly...this is a new change from Facebook as of 4 days ago. This is not a hoax, don't believe me? Read your timeline from those years...yikes! They look like wall posts.....they are not! There's an easy fix--when you're in your own timeline, just click on the year on the right (2...007, 2008, 2009) and you'll see a box with a bunch of friends' messages and a header that says 89 people have written on so and so's timeline--hover over the right until you see the pencil, click and select hide from timeline. Do that for each year. BOTH parties have to delete or it will show.  This makes me more aware of how your security is in their hands at facebook.
