Profanity Filter For Me!

Hi all

I’m looking for a word find/replace filter similar to a profanity filter. I’ve just started my blog, and I’d like to find a plug-in that finds potentially “scandalous” words in my blog posts, and replaces them with something “search engine friendly”.

e.g should I type the word “bugger” into a post, I’d like a plug-in that would change that word to something that isn’t picked up by SE or filters, e.g putting <span>’s around certain letters, introducing other letters that have style=”display: none” attached to them, so bugger would become:

b|span class="hide"|u|/span|gg|span class="hide"|e|/span|r.

(Excuse, the pipes==less than & greater than.)

Or something similar.

If anyone knows of an existing plug-in then I’d be grateful. Or if anyone can create one for me then I’d happily pay some greens. I can customise in PHP to an extent, so that’s the level.

TIA.

Natalie.
