Spam and the Village Hall
It seems that the Wordpress forms are using a "plug-in" called Jetpack - also by the same authors as Wordpress.com and Akismet
I have to admit that WP and Akismet, possibly because of Jetpack, do a pretty good job of blocking spam emails. This is at the same time as the fact that WP sites are a huge target for spammers. In fact I was a little concerned that opening up my sites with forms would expose my input to abuse. However, with this design template I can make my custom pages look sufficiently similar to the Wordpress theme that most users would not know the difference.
In fact I would hazard a guess that many would not know that anything had changed from Colin's design.
Update: I changed the Subject in the Jetpack contact form on 8 March and no spam as yet on the 9th.
Google and other search engines will see this type of spam as "unhelpful" for the user experience of a website.
