Following my review of Defensio, Michael Hampton (of Bad Behavior fame) left a comment on the same post assuring that Bad Behavior would run just fine along side Defensio without causing any sort of hiccups for the latter. My thoughts exactly – since Defensio operates more or less on the same principles as that of Akismet, whereas Bad Behavior’s modus operandi is a bit different.
Instead of filtering spam and diverting them to a hold (quarantine), Bad Behavior entirely denies access to your site to suspicious IPs (the ones from where there are an excessive number of requests within a short period of time). Logically, this shouldn’t hamper Defensio in any way. Michael’s comment had got me wondering if I should enable BB again and today’s incident gave me a hard shove in the same direction.
What happened today? Well… Defensio went for a toss, and that too for a good while (it’s till not back up as I’m writing this post). This is the second downtime I faced ever since I installed it, though I’m not certain of the cause. It may be because of lack of infrastructure to handle such high volumes of network activity or some other temporary server outage. Either ways, what I faced was a massive spam flood – the likes of which I never encountered while using the Akismet + Bad Behavior combination. Luckily, I had comment moderation turned on! End result? Here’s a snapshot of my inbox. See for yourself 😀
Motivation enough to start using Bad Behavior again? I totally think so. Besides, as Michael pointed out earlier, it can’t hurt Defensio in any way other than denying their spam-harvester its share of spam.
