I have never heard of a blackball list at large SV companies unless it was something egregious that person did. Things like starting a fight with security, coming to an interview drunk, etc. will get you on it.

But what side of the story did you get? The side of the person doing the blackballing or the person being blackballed?
Just as a counter example (there is a link in this thread to exerts from a employment lawsuit against Google), one Google Manager is quoted outright...
"...I don’t care if you are perfect fit or technically excellent or whatever. I will actively not work with you, even to the point where your team or product is impacted by this decision. I’ll communicate why to your manager if it comes up. You’re being blacklisted by people at companies outside of Google,You might not have been aware of this, but people know, people talk. There are always social consequences.”
What is the offense? Apparently holding republican/conservative values.
What party culture? I worked at Google in Mountain View and never saw any of this, nor "brogrammers", nor endless mandated/encouraged overtime, or most of the other stereotypes that seem to perpetuate themselves.
