WTF @ new age spam

I am noticing an increasing number of ‘weird’ spam comments on one of my posts. Due to the fact that they are worded almost perfectly makes it impossible to catch with a filter like mollom. Look at this for example:

Impressing statistic from Drupal but I think this is a very rapid “market” and this statistic is even after a day old. Regards, Erik
