How to avoid s p lit up wor ds?

[Chris Wilkes]

I'm starting to get a lot of spam that looks like:
	buy  to ner  car tri dg es
where the bad words are split up into 2 or 3 letter words.  Since BF
throws out those words it could get by.

What can BF do to combat this?  Granted most spam list that has to
contain a URL in it that can be caught.

Maybe a simple frequency count of spam words vs larger ones would catch
this?
