I don't use it as they have in their terms and conditions that they own all rights to every picture you post. You turn over all permissions to them to use your images as they see fit in advertising or whatever they choose. Even after you delete your account.
I Instagram but not trees usually. name is the same on there. sure they have the right to use your images but the resolution is so low it hardly matters. really, they only look decent on a phone-sized screen.
