are actively antagonistic. Not that hard. That said, my filter is set to zero, and my ignore list includes 3 yewt trolls, one REALLY annoying baseball guy, and two twitter accounts, and I frequently clear out my ignores so I don't miss anything, and then just add (re-add? I don't pay enough attention to the yewt trolls' names to remember who the repeat offenders are) anybody who gets really annoying, until my next get-out-of-jail purge.
Shouldn't be that hard to figure out that people want to actually enjoy what they're using for entertainment. CB isn't a job (well, it is for most of you, not me), you don't HAVE to deal with the annoyances that come with it.
