ZDI: "This vulnerability was discovered by an anonymous researcher."

[00:23] < constant> I found out about www.zerodayinitiative.com sometime ago.
        After looking at some Firefox reports back when I found the site, and
        now again, it strikes me that Firefox vulnerabilities are reported by
        anonymous researchers...
[00:24] < constant> i.e. someone introduces a bug to mozilla, then reports it
        to ZDI, and then gets paid for the bug being fixed? :)
[00:24] < constant> Or maybe not introduces, but finds a bug in a patch
        submitted by a contributor, but puts an r+/sr+ on the patch
        nonetheless?
[00:25] < constant> I mean, why would you not want to get credit for finding
        some mozilla bugs?

[00:28] < constant> any comments?
