Be aware that SFS will give false positives (anyone using Tor for example will be blocked, since SFS lists Tor IP addresses) unless limited to email addresses.

Limiting the number of posts a new user can make and placing posts from new users with an "excessive" number of links into a moderation queue should cut back on spam without too much impact on new members.

The best option would be to allow (senior) forum members to label posts as spam with posts being removed/hidden globally if labeled by enough members.
