Why is there no urine in the swear filter?

The naughty word for a wee-wee still seems to have been omitted from the filter.

Can anyone explain why?

Quite bizarre when things like this get caught up in it:

Shorpe.

Piss is no longer a swear word. It got deleted by the passage of time. It's in the same category as bloody, damn, hell or other words old people think are swear words, but aren't.

The word piss-pot is in one of the brothers Grimm tales so if it's safe for a children's book then it should be safe enough for here
