advice Stolen Domain Database/Registry

[domainmisc]

there needs to be some sorta official stolen domain database/registry

I have seen this mentioned multiple times, so I am working on a stolen domain/registry website as a project. Before I get to far into the project, I am looking for some advice as to what kind of features should be implemented. Thank you in advance for any ideas you have, I will implement the ones that the community says is the most important
