Taking into account other's replies, e.g.revdiablo's one, I think you're right. Actually I hadn't noticed the stress on exploits (or more generally, vandalism) and I thought it to refer to people running others' programs hardly knowing how to code or as you say, without knowing how to code at all.

In some sense my question still applies to such people (losing the emphasis on the damage intentions) if only you take into account all those who blindily used, say, Matt's scripts thus contributing both to Perl's diffusion and to that -indirectly- of cargo cult perl programming...
