If there are .svn directories still present, it's likely that they just copied a working copy to their web server. You're supposed to use "svn export" to create a "production" version without the .svn directories. Or just delete them. Either way, this is really VCS misuse more than anything else.
blocked or not, utilizing svn export is a 101 level thing. Who runs these places??<p>Another reason to love git, one single .git folder in the project root.
