My impression of blacklists is that they're much more systematic and pervasive than that. If you're an individual contributor, I think it'd be really hard to become so infamous that your manager's manager is complaining about you to his peers during a golf game and they remember you. Also, if you're writing your Representative about some kind of abuse or malfeasance, you could always use and assumed name (and say you're doing so to avoid retaliation).
