Currently the spam blacklist has a very large turnaround time. I added pillsbook.com http://meta.wikimedia.org/w/index.php?title=Spam_blacklist&diff=99417&oldid=99414 http://en.wikipedia.org/w/index.php?title=PHP&diff=10231814&oldid=10231802 took place half an hour later.
Does it happen every time? If not, it is probably a transient memcached error, or possibly a sychronisation problem. SpamBlacklist uses the edit filter function itself to immediately refresh the cache when the list is changed.
Yes, I reproduced this twice with nonsense domain names. In fact I could not find an instance where the blacklist took effect immediately.
Fixed in CVS and live on site (tested).
