Well... By definition, you can, just as you can use the word cock or even Dick. HOWEVER,
If you use those words in a derogatory or vulgar manner, you can expect that someone whose name is in their postbit in black text is going to have a couple of words with you.
In my estimation, the member is being appropriately cautious in self-censoring, and I appreciate the effort to make my job easier.
Richard is Dick, but please don't call him "a" d**k here on INGO.
You can cock the hammer of your wheelgun. Please do not use your wheelgun to hammer anyone's (ahem). (or at least, if you must, use different words to tell us about it on INGO.)
You might have pricked your finger. We don't need to hear about you fin....well, you get the idea.
This is where the filter fails us, and using it on those words, in those contexts, would more draw attention to them than minimize it.
