Spam Form Filling Despite reCaptcha

Advert test
#1
Recently I've been plagued by spam bots (all from China) filling in submission forms with details of Ugg boots, jewelry and other junk. They appear to somehow be circumventing the reCaptca somehow. Anyone else having these problems and any solutions? I have also banned several IPs, but they seem to have an infinite number of IP addresses.

If the site is in PHP there are a few open source and commercial "firewalls" that you can use
They're basically scripts that check a number of elements of the UserAgent, IP etc., and if they detect something weird / dodgy they can block them ..
Alternatively you could try using something like MaxMind's Geo IP services to block certain countries entirely ..
