I've turned on captchas as a requirement for commenting because unfortunately I've seen a huge rise in spam comments lately. While Blogger is pretty good about filtering them out so that they don't show up on the site, I still get an e-mail notification for every single one of them and it's been getting pretty annoying.
We'll see if this helps - if not, I might have to turn off anonymous commenting instead, which would be a real shame as I have quite a few readers (guildies etc.) who don't have any kind of account to sign in with and who like to just leave their name.
So let's hope that captchas do help with my spam problem - even if Blogger's have convinced me that I must be at least part robot, considering how often I fail to enter them correctly myself.
Apologies for the inconvenience.
