In fighting the spam wars around this place, when the waves reach hurricane level, I turn on the anti-spam word for comments just to give the old interwebby tubes a rest. That kills trackbacks, though (and the Bad Behavior plug-in kills a lot of legitimate 'bots access to the site). I've tried turning it off again to see if the frenzy of spam has subsided.
UPDATE: Nope – I had to reactivate it. They were hitting so hard that they caused a CPU suspension for the site.
What blogging platform are you using? If it’s WordPress, make sure you have installed and activated the SpamKarma 2 plugin.
It’s stopped 98% of the spam I used to get.
OK, I’m giving that one a shot, I just don’t want to block some ‘bots that are actually beneficial – which is what Bad Behavior does. Let’s see what SK2 does.
So far, it is actually working well. It is killing them and still letting the traffic in. I haven’t seen if it is killing trackbacks yet.
