Not so safe words still present - mostly due to the need to use word-stemming to find them perhaps?

[anon1793]

Such as:

f**kers
f**kin
f**kwit (full only)

And also various words starting with sh*t in the full list only.

THere could be more, I haven't checked anything else.

Edit: on reflection, maybe even conventional word-stemming is insufficient (it's not the usual -ing / -ed type gramattical ending), perhaps just a prefix and/or substring search could work though.

Hmm, it may result in too many false positives, though -- I'm open to suggestions.
