Usually just skipped tinyurls entirely.

All the more reason to do your web browsing with Firefox and the NoScript
add-on. This lets you access websites with all scripting and plug-ins
(flash, etc) turned off. You can then easily chose whether to allow a site
that "needs" those features to do so, either temporarily or have them added
to your permanent list. It goes a long way toward stopping pop-ups and
web-based malware.

Try it.
