So Ive tried everything to stop spammers on my WPMU site... Every plugin, every tip, every hack... Nothing works!!!
Finally, I got so tired of it I decided to block entire countries! Including Korea, China, Russia, India, Turkey and Vietnam. I found lists of their entire IP address blocks and put them in my htcaccess.
You can get the lists here
I only deny then access to the wp-signup.php using the following:
All the IP blocks go here
It works! Not a single splog!!! I know you've probably heard this hundreds of times before... But this is the only thing that has worked for me. Over 100 splogs a day to zero!
What I want to know, is there a way I can redirect them to a explanation of what happened? just in case they are a real person...
Also is there any downside to this I dont know about?
My htcaccess file is huge at 200KB is there any way to make it smaller or does it matter?...
