It has come to my attention that one additional step is required to help you manage comment spam, if you are having a problem. Go to your Dashboard, select Jetpack from the left hand side, and then select Akismet from the submenu:
Click the big blue button that says “Use this Akismet account.” It’ll take a minute to work, since it involves patching some things up on the backend and hooking them into some other networks. But! Once it’s done, you’ll be hooked into my Akismet, and will suffer no more from comment spam.
After it’s done hooking up the spam plumbing, it’ll take you to a dialogue that will let you choose whether simply to discard comment spam, or whether it should put it in the spam folder. The default is the spam folder; I recommend banishing all that spam straight to the fiery pits of hell. It’s your choice; do as you please.
We have our first bona fide network problem of the semester: comment spam. It’s a real issue. The first line of defense is going to be to enable Jetpack/Akismet for all of your blogs. I am doing that presently.
Once I do this, in theory, you should be plugged into my Akismet. In your site dashboard, under the Jetpack menu, there should be an Akismet option. It will tell you how many spam comments it stopped. It should also—and this is the important part—have my Akismet API key in the “Settings” box. If that is there, the plugin should be working. (If it’s not, please let me know. It’s hard for me to recreate what you guys see.)
In theory, this should be enough to stop most or all comment spam. But here we are, on the network, in a relatively untrafficked corner of it, and here we are, with comment spammers. Welcome, I suppose, to being networked.
