I had a post removed today for using the word "spook" in reference to government agents, a common usage that I see around the site, because it is a racial slur, although ive never seen it used with that intent (not that it matters), and it only gets removed maybe 10% of the time. In order to be consistent and not offend any comrades I would propose adding it to the word filter so its removal will be uniform and not open to mod interpretation.
I remember using that term and people from more Southerly parts were given a start. I was referring to the President coming to town and the this small area I was in suddenly teeming with agents. It does seem a regional slur, but a slur nonetheless.
