Er, no. HN is part of YC's screening and application process. You have to have an HN account to apply to YC and if you have been an active user, your comments here basically become part of the screening process. It is part of why HN is better behaved than a lot of forums: Being an asshole here can help close doors for some folks which are potentially worth million$.*

* At least, this was all true last I heard. I have not looked at their application or application rules/process recently.
