To be entirely honest I misread the swearfilter replacement code. So, yes in context it was an overreaction.
The principle of remembering that, internationally, words are occasionally offensive in some countries and not others stands, however the word you used was in the filters to pick up it's use in another context, so my apologies for the tone.
Anyway, back on topic. I've taken photo's of fish in shops before so that I could go away and identify for myself what the fish really was before I considered a purchase, and not only in P@H. I've rarely been challenged and my reason always accepted when I did.
