I've also deleted, banned new members aka spammers, and banned their IP addresses, several time myself in the last few days....

I think I remember JCO said he used to look at their 'on-line name'...and he checked 'where' the IP address was comming 'from'. I think he was able to cut out alot of this 'stuff' before it even happened. Of course, he's pretty busy now a days..
