www.brickalo.com gets spammed!

It looks like my www.brickalo.com website has been found by some sort of SPAM robot.  I've kept an eye on the backend system which does not appear to have been compromised - any email addresses entered in to Brickalo are not used and the system does not send out any emails (there is no email server installed on the backend).  So it does appear that robots are now playing with Lego!

In the image above, probably 75% of the Rainbow Lego Towers have been built by some kind of spam robot!
