I didn't want to have to do it, but it's getting ridiculous. I have started to close commenting on old posts.

The amount of comment spam is growing daily, I had to delete almost 100 spams today, which hadn't been picked up by MT-Blacklist unfortunately.

So from now on, after 14 days of a post being written, commenting will be disabled on it. Sorry if that inconveniences anyone, but you gotta do what you gotta do.
