What is ET CURRENT_EVENTS DNS Query to a .tk domain - Likely Hostile?

See this IDS alert on a urlquery scan result for a site involved in Yahoo spam content:
http://urlquery.net/report.php?id=117837
What is this rule alerting to?
Both co.cc and t.k are very scam sensitive, co.cc is blocked and .tk is not?
Well, dot.tk and .co.cc domains are two of the most abused services. (APWG Global Phishing Survey 2H2010)
