Philip K is one of the words on the forum the profanity filter, Albert. Regrettably, it can be both a persons name and another word for schlong. Schlong isn't on the filter. So if you want to use the Philp K word in a derogatory manner, just call your target a great big schlong head and it will pass the filter. But Don't ever call Philip Philip K Schlong. That would just be silly. See also Grayson and Van Dyke.
I have tried removing certain words including ones that can also be a name. Unfortunately, people decided to go out of their way to abuse the privilege. So, I rarely bother to make any more changes to the word filter list.
