The software uses a parser like many other programs (MS Word, etc.) that don't recognize context of the word but the word or part of the word itself. Thus and such, anything that comes close to the word that is "deleted" is probably going to appear as ****. It's because when you tell the parser to find and destroy certain words or phrases (like annie mentioned with the pharm companies), it's non-discriminatory towards the content in which the word is used.

Hopes this confuses the hell out of everyone since apparently today I make no sense...
