Splog users & Auto-move wp-signup

The Anti-Splog plugin has been working really well to catch the Splog but I wonder if there is anything to prevent it from even getting caught. I did a search and added the list of “banned” addresses but other than that is there anything I can do?

Also, even though the splog blogs are marked as spam the users are not. Do I just manually mark them or is there an automated way to do this when the blog is marked?

Finally – we have some hard coded links going to wp-signup.php – if I use the auto move option does it change the address or just the location. I don’t want any of my links to be bad.

Thanks so much for your help.
