On iOS I've been using "Bouncer" for the past several months to filter messages using regular expressions. It's been doing a great job so far for me.

I’ve been using a similar app, though the one I use doesn’t support regular expressions. Not really sure why this isn’t built into iOS. When used with the right list of terms, the app works well.
