Tried to install SpamBlacklist. Used the simple setup suggested for localsettings.php (without including array). Did not get it to work.
You could try addressing the issue directly to the abuse staff at the source ISP:

I put the offending IP address into the ARIN whois web page (http://www.arin.net/whois/) and then see which IP it's coming from. ARIN will tell you if the IP is allocated in a smaller block and give you a link to a further IP search web page.
I see you've been putting all the offending IPs into the blocked IP list. That has limited value since the IPs of spammers change so often.
You could try installing a Captcha extension. If the spammer is a bot, they tend to be stopped by that.
