@Claygp: Have you verified that their IP/Email/Username are in fact part of the SFS database? Have you reported the "Legit People" to SFS so they can be investigated and potentially removed from the dB?

As I've seen the "I have to disable this mod" statement a few times in the last few weeks, it is probably worth reiterating that you do not have to block users that are caught by SFS. Instead have those users put into a more restrictive usergroup which either has their posts validated via Akismet or has it's posts manually validated by your site moderators. You can then set an automatic promotion strategy (based on time, # posts, etc) to move them to a less restrictive usergroup.

This gives you the best of both worlds... even in the rare case there is a false positive, your users can still register and post, while at the same time having peace of mind that content is being vetted before it is being presented to your users.
