Spammers exploiting trust in shortened URLs

• byrneseyeview 17y ago
  Who "trusts" bit.ly or tinyurl? I trust them about as much as I trust http:// http://.

    Point is that you can no longer use the url's hostname as a document feature for spam classification. You have to actually fetch (or at heast HEAD) the url itself. Also, I called this one too.

      This is true, but it's also true of any site that allows user-generated content. I would assume that it's easier to detect that bit.ly/gibberish leads to viagraaffiliatescam.com than to detect that randomblog.blogspot.com is a splog with 400 links, one of which goes to viagraaffiliatescam.com.
