I installed those addons and configured Akismet.  I am still getting 100 or so registers a day from evil users.  In fact when I made my post the other day I had around 7000 users, today I have almost 9000.  So it is being hammered by spam bots. 

I'm curious as well if there is a simple way to clean these users out.  Even if I am able to solve the problem of spam bot users I still have 8500 users who are illegitimate.   This sfs.php script can find them but provides no easy way to delete them except one by one.

I love this script however it has a few issues.  First I know there is likely 7000 fake users on the forums. 

Issues:
- seems to give different results on every refresh
- only gives the first 3-5 results
- no way to mass delete


I'm basically at the point where I'll just have to wipe the entire board.

Yes I have all the captcha and anti spam extensions commonly used which seem completely ineffective.
