I like that it allows us to be anonymous by using a throwaway email address. It makes it easy for whistleblowers to send sensitive information without fear of retaliation. The interface is confusing at first, but once you get used to it, it's very useful. We've been able to use it for several years now with no problems.
There are some bugs here and there, but nothing major. Anonymous whistleblowing is an important part of our organization. We can't afford to have secrets in our organizationโฆ
