I generally find it worth it for the simple risk that you may end up breaking stuff without anything malicious on behalf of the site.<p>E.g. cut and paste a command and get a linebreak in the wrong location and the &quot;rm -rf &#x2F;var&#x2F;tmp&#x2F;foo&quot; turns into &quot;rm -rf &#x2F;var&#x2F;&quot;. Fun times.<p>These days I&#x27;m more and more often just spinning up temporary containers as well. Not so much for security as to avoid making a mess of my environment with all the stuff I&#x27;m testing. So trivial to start out with a &quot;docker run --rm -t -i ubuntu -v &#x2F;some&#x2F;suitable&#x2F;host&#x2F;dir:&#x2F;mnt &#x2F;bin&#x2F;bash -l&quot; or similar to get a fresh container with a directory I can dump anything I decide I  want to keep in.
