offensive/rude word <<bleeping>> for posted text??? is there a plugin / existing mechanism to do this???

Hi all,

Just wondering whether there exists in ruby, or rails plugin, an offensive/rude word <> feature?

For example if accepting text for a blog if there was a rude word it would replace it with <> or XXXX.

Cheers

people find bayesian filters useful for this.

Or,
you could just gsub it out.
