If you signed up for SAV using Google you may be giving your information to the public and the trolls who scan SAV. To protect yourself click on your profile icon on the top right of the page then go to "My Account." Under "Display Info" pick a unique username. Then, scroll down to "Account Settings." Click "Edit URL" and change that to your profile name. If you don't do this, it could display your email address which trolls can use to contact you (if you signed up via Google).
