I tried to ignore the increasing flow of comment spam on my site, but the annoyance surpassed the threshold. I was flooded with over a hundred comment spams today, and so I've had to take a few steps to address the problem. I installed Jay Allen's MT-Blacklist and will force users to preview and approve their comments moving forward. I haven't gone so far as to install MT 3.0 yet to require TypeKey registration, but if these steps don't work, that won't be far behind. Spending an hour deleting comment spam is a slow burn.
I'm reminded of Eric Stoltz's speech in Pulp Fiction about what they should do to people who mess with another man's car: "They should be f***ing killed. No trial, no jury, straight to execution."
Sounds about right.
