While this is a valid concern, I think that anybody cutting and pasting code should know what that code does, as in read it and understand it prior to cutting and pasting. Anybody who suffers faults from cutting and pasting code at random only suffers because they didn't bother to read that code first. I think that this should serve as a lesson to people who use snippets, that they should read those snippets first.
