After you deleted the user, did you check the ACP's list of banned IP addresses?

Did you check the IP addresses of those users?
Generally, I only ban an IP address if I get spam from it multiple times. IP addresses aren't always fixed for a given PC, so the IP address that belongs to a spammer today could belong to a legitimate user tomorrow.
If the usernames are always similar, I use the Disallow usernames
Also, if you're not using the Q&A CAPTCHA, you should check it out.
