    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.

    You could try banning an IP address range or looking for a different Captcha

    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 ..

    Yes I had considered banning China... but I thought that was a bit harsh.

    Blocking certain countries completely reduces some issues to practically zero ..
