Slashdot has spam but only in the firehose.<p>View the firehose at 'black' level and you'll see more spam than on hn, just a random sample:<p><a href="http://slashdot.org/firehose.pl?op=view&#38;id=8811130&#38;art_pos=3" rel="nofollow">http://slashdot.org/firehose.pl?op=view&#38;id=8811130&#38;a...</a><p>The firehose is equivalent to the HN 'new' page.<p>If you only look at the homepage on HN you will never see spam.
