A word of warning to anyone upgrading to Mastodon 1.3(.1)!!!

Starting with 1.3(.1) Private posts will federate! But they don't do so securely! Warnings are built in but be aware that if you have followers on GNU Social, Friendica, or postActiv then they will **NOT** know that your post is marked private/followers-only!! And they **will** be able to boost it!! Once they do so, it becomes a public post

This is not opt-in, it just happens post-update

If this worries you, go audit your followers
