List of known IP's from which Spam originates ?
 

I've been facing LOT of spammy registrations and each day i end up wasting my time physically removing spammy signature droppers, banning them etc.

I already use Q&A option on registration yet most people join only to drop links in profile/signature/first post:(

Do you have a readymade list of IP addresses that are known offenders / spammers whom I can ban as a pre-emptive action?

I feel overwhelmed by this spam trouble..pheww

Please guide....

Thanks
