How can I filter out profanity in numeric IDs?

Question

I want to use numeric IDs in a web application I am developing... However, as the ID is visible to users as a URL, I want to filter out profanity. Things like (I'll leave it to you to figure out what they are):

page.php?id=455
page.php?id=8008135
page.php?id=69

Has anyone solved this? Is this even a real problem?

Does it make sense just to skip numbers in my database sequence?

Answer 1

How about you using GUIDs? That would encode the actual numbers. I would bet most users don't even notice what is on the url.
