Hi all,

Esben from CrowdCurity here. First of all I want to say thanks to NLNICO for maintaining this nice list. Secondly I would like to add a comment to the spendbitcoins.com case. I understand that it can be frustrating from a tester's perspective when a potential vulnerability is rejected by the site owner. However allow me to provide some general insight to how CrowdCurity works - which might help clarify the matter.

CrowdCurity is a marketplace for bug bounty programs. I.e. we enable businesses to to connect with security researchers.
 
Currently the platform allows for the business to give feedback to the tester, and just like any other bug bounty program you would find on the web, it is the business who decides what is eligible for a reward. In cases where a researcher can present proof of any misuse of the platform by the business, we will try our very best to mitigate and in worst case stop the bug bounty program. However we don't want to be the judge on specific vulns but rather want to build in features that allows for the community to sort potentially issues via ratings and feedback mechanisms.

We are currently building features that will allow researchers to provide feedback to the business and raise flags to warn other testers of a specific business conduct. This will be done in order to create a platform where both businesses and researchers can improve based on the feedback that they get. Basically we are looking for a bottom-up solution rather than us being the judge on potential conflicts.

Once again we want to thank the security community for using our platform and helping improve the overall security for bitcoin businesses.
