"suite101\.com" has been on the blacklist since November 2006:
<http://meta.wikimedia.org/wiki/Spam_blacklist?diff=472751>. When I
tried to create a new page containing your link, the spam blacklist
correctly caught it. It sounds like the spam blacklist is (or was)
being enforced sporadically.
Yours cordially,
