Meh, the filter is adequate for its job. It's perfectly possible to make extremely offensive and/or threatening comments without ever using a bad word, so it's not going to prevent you seeing things you don't like.

Also, any excuse to quote Stephen Fry

Swearing is a really important part of one's life. It would be impossible to imagine going through life without swearing and without enjoying swearing... There used to be mad, silly, prissy people who used to say swearing was a sign of a poor vocabulary -such utter nonsense. The people I know who swear the most tend to have the widest vocabularies and the kind of person who says swearing is a sign of a poor vocabulary usually have a pretty poor vocabulary themselves... The sort of twee person who thinks swearing is in any way a sign of a lack of education or a lack of verbal interest or -is just a f___ing lunatic... I haven't met anybody who's truly shocked at swearing, really, they're only shocked on behalf of other people. Well, you know, that's preposterous... or they say 'it's not necessary'. As if that should stop one doing it! It's not necessary to have coloured socks, it's not necessary for this cushion to be here, but is anyone going to write in and say 'I was shocked to see that cushion there, it really wasn't necessary'? No, things not being necessary is what makes life interesting -the little extras in life.
