I approve all of my new registrations, and I really haven't had a spam problem. Doing the approvals is a pain in the neck, though. I run the emails through Google, and any hits from stopforumspam will usually show up there. In many cases, you can see other forums that they belong to, and whether they are legit or not. Suspicious IP addresses are run through stopforumspam directly. I find a few, but not all that many. I'm getting probably 300 new registrations per month, so it is very time consuming for me, and frustrating for the new registrants who want to be posting.
