You can protect against these attacks and maintain your privacy by doing the following:

1. After you take a picture, open that image on your computer and take a screenshot of that image and crop as needed. This removes all camera metadata.

2. Use a program for PGP encryption. Type out your message on Notepad or whatever, encrypt it locally, then paste the encrypted message into the website's message box.

3. Use a randomly generated username and password. Generate a different username and password for each site.

Don't break the law, kids!
