We prefer real security, responsible disclosure and community based unity.
In other words, if you find a bug, please tell us - but don't expect a huge payout, look at our prices - we are clearly not drowning in cash here, we are just trying to provide a trustworthy and sustainable service.
When that is said, one of the reasons why we work so slowly, is that we build our software with a security first mindset and strive for perfection in all aspects of our platform.
We do not tollerate any kind of security probing on our production systems, and we will use any available means to stop you if you do not respect this. However, feel free to respectfully poke around in our sandbox environment.
