I had a rule note on this from before. Haven't got to it yet. Basicaly
because of the FP rate. I'm going to write a few quick rules that look for
letterzeroletter and letter1letter. You can see why the FP rate would be
high. But I would score this low. possibly combine some of the rules. Like
looking for multiple instances of the rule. 

It is easy to write a rule for some of the better knowns ones like
/(f|ph)(o|0)t(o|0)/i
but with all the ways of doing OBFU it would be kind of big. 

Your spam was a nice example.
