I know spambots are becoming pretty smart, for example, some can detect something like "mto[AT]domain[DOT]com" and decode it into an email. Search and replace thing...
So I wonder if using the same technique they can remove the [:"blue"]+[/] from +mailname+'@'+mailaddy+ and so on...
That one is very similar to
this other one I just found. Though this one is a little more complicated, take a look.
