Well we were lucky for a long time, and had very little spam, but now apparently spam is increasing. So I have re-instituted spam protection. What it means for you is that when you click "Submit" on a comment or post, you will see a "captcha" form, asking you to type some letters. If you get them wrong you can try again. When you type them correctly, it will send your post through.
It's a little more inconvenient but will help keep things neat around here.
On my other site, I get hundreds a day sometimes, so I shouldn't complain!
