.htaccess and spammers

Postby david » Fri Feb 11, 2011 4:02 pm

Dear Brothers and Sisters

You are probably aware that we have been under assault from spammers for a while now. I have been deleting about ten accounts a day. Myself and moderators have been culling the spam throughout the day. I think that we have reduced it to the point that the typical reader can go for days without encountering spam, but occasionally it does get through.

Obviously it is not possible to spend all day just watching the forums waiting to eliminate spam and spammers. So we have been using some automated processes to assist us. Up until this morning, I was pursuing an approach of trying to ban access to all visitors from Russia and the Ukraine. I feel that this was partially successful, but I think that the problems associated with this approach are so obvious that we really do not need to enter into any discussion.

I am going to try a new approach, but I am seeking feedback.

From now onward, attempts to ban access to the forums from Russia and the Ukraine is being replaced by denying access to a much more targeted list of rogue IPs. This list is small and more focused. Furthermore it denies access to all of chandrakantha.com, not just posting to forums.chandrakanth.com. Therefore it may reduce the incidents of spammers harvesting emails from the teachers/performers database.

I hope that this proves to be effective at reducing our workload, and reducing the amount of spam which slips through.

As always, suggestions and comments are greatly appreciated. I have posted the list below for all to see.

Peace

David Courtney
