Grepping out naughty words in randomly generated text definitely strictly weakens the information content if you're using it for a secure application but is often necessary. In the early dotcom era the company I worked for were about to go live and the final step was demoing the end to end flow to the ceo. I had done the back end stuff and hadn't paid much attention to the front-end. The person who did the account creation process wanted to nudge people to generate memorable yet strongish passwords, so when it created your account it would generate with a random password which he did by choosing 2 four letter words at random from the unix dictionary and putting a two digit number between them. He ran that past me as an idea and I thought "yeah, good idea" and didn't think more of it. However he forgot to first grep out all the naughty words so when we demoed it to the CEO/non-technical founder both of the words in his randomly generated password were swearwords.
