NoScript is a whitelisting system, not a "I never use JavaScript" system.  You load a page and if it doesn't work, <i>then</i> you enable its JavaScript content through a convenient menu.  (It even bolds the scripts that are likely to cause problems when not enabled.)<p>In this case, the site works fine without the clipboard-hacking JavaScript running, so it just stays disabled and the OP doesn't get random data from a website written to his clipboard.  If he wants that functionality, though, it's one click away.<p>What's quaint is trusting websites to run arbitrary code on your machine, as your regular user.
