At 6:26 CET this morning, one of my sites was hit with (at least) 44 attempts to leave spam posts advertising "blog hosting" at wordpress.com.
It only lasted for a minute and IP addresses were from all over the world (China, Indonesia, but also ones belonging to Comcast). So this was your typical botnet in action.
Not sure what the point was, though. Either they wanted to discredit wordpress.com (i.e. a joe job). Or it was simply test spam, like we've seen it for all major search engines in the past. Odd in any case, though ...
Damn Spam!
