I generally don't really care about the copying of code/posts as long as the content is interesting (and prefererably attributed)... but... as perlmonks is more or less a finite resource of feedback & help for the general public and the posters mentioned also have a tendency to do "drive by posting" - i.e. post stuff they quite obviously don't understand and/or aren't interested in - I would have to agree.
As far as the specific sanctions, I would say just disable the accounts. It's probably as effective and a lot less work, since anyone can start a fresh account to get around any other sanction.

Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
