[Full-disclosure] Websites vulnerabilities disclosure

[offtopic <offtopic@xxxxxxx>]

Hi List.
I need your opinion.
Recently I found multiply vulnerabilities in several sites. some sites behold 
to security-related firms but not software vendors. I'm trying to contact that 
companies under rfpolicy several times but don't receive any response on 
receive something like "what injection your talking about?". 

I want to know - is it "ethical" to use standard vulnerability disclosure 
policies to public websites? Which fird-party can't be user as coordinator, 
like CERT/CC? 
Or in other worlds - who should care about Web-sites security?
Thank you.
