You're having trouble encountering quoted posts? If we didn't see quoted posts (of ignored users) then we would never know if the user deserves to be un-ignored.

https://bitcointalk.org/index.php?board=167.0I agree with LaudaM. Many users have been altering their posting behaviour, not to mention the people maintaining an ignore list may add there some others that between them there's a personal difference. Maintaining an "unprejudiced" list is a hard task to do and even if your cause is noble, you're still getting some "uhh" hits. Comes with the package.
