No, I use the term to mean taking the enforcement of rules, whether
legislative or not into their own hands. The vigilantes from the
US racist south were not taking the 'law' into their own hands when
they lynched blacks, they were imposing their own rules on society
through force.
Oh stuff and bosh. As a user of third party blacklists, _I_ am the
vigilante imposing my will and my rules on who can send email to my
users. I am the censor. The blacklist is not the censor nor the
vigilante. Just a provider of some of the information I use.
