Perhaps could you limit the number of accounts that can be created from an
IP address within a given time period, or I've seen sites that when you
signup have a picture with a random number "hidden" in it to work around
automated signups.. 

I don't know what more you could do (probably digressing a little here but
I'd be interested what others would suggest), but I would say that if you
allow spam but try to limit the rate rather than stop the spammers you will
end up blacklisted which tends to not be good for business plans :-)

good luck with whatever you do!
