This is NOT being upfront. Without coming into the comments I would not have known you'd try to poach my candidates.
It's not like this is tucked away in the Terms of Use behind complex legal language. It is stated quite plainly on the landing page beneath a large header reading "Why is it free?"
This is a huge deal to any business that takes themselves seriously, and when you bury the lead like this, it makes me not trust you. As I said before, this detail should be under the "pricing" text, since that's what every person who might use this service is going to be looking for, once they understand the basics.
And I'm a person who might have used this service. I keep a special gmail account for processing hiring applications. I'm their dream user. And I was misled so far that I don't trust them.
