I don't really fancy listing all the ways I know to obfuscate links into 
themes, as even though I find the practice shady listing them all would 
provide an easy-listing resource for people wanting to do just that.

Of course if you are serious about writing a plugin to defend against 
such things, I'm sure if you google a bit you will find all sorts of 
references to hidden links and how they get there.
