uses Imgur without providing information to the end user on Imgur's Terms of Service. There must be a tickbox which is not selected by default, so that a user can only upload to Imgur IFF
they have agreed. Otherwise users of this software are having their data used in a way which they may not have agreed --- an invasion of privacy.
