2. Do not accept hotmail, gmail etc addresses as valid. Require a "real" email address (lists abundant on the net).
3. Use captcha to slow down bots
4. No more than 1 signup per "person" in any 24 hour period to slow down bots (look for commonality - the birth date above is one example you already have - b-class IP and UA matching work well. Insist on setting a cookie etc).
5. If spam is a problem, again look for comonality. New member signs up and minutes/seconds later drops a URL in the forum? It's very easy to detect and trap that. Have a pre-moderated area to dump "suspect" posts.
