Along with the upgrade to MT 3.31, I also installed Jay Allen’s Comment Challenge plugin. It’s a very simple, and at least for the time being, very effective anti-spam plugin for Movable Type, that adds an extra compulsory field to the comment form.
Right now, this means that when commenting, there’s an extra box where you need to type the word ‘sausage’ in order to allow your comment to be accepted. Spambots aren’t yet intelligent enough to pick up on these and so the field either gets left blank or isn’t even submitted at all, which the plugin then marks the comment down as junk.
At present, you can miss the field out and your comment will still be submitted, however, it’s likely that I’ll have to fish it out of the junk folder (and I’ve already mentioned today just how many junk comments I’m getting). I will probably change this soon though – in future, you’ll be told that your comment wasn’t submitted and asked to fill the field in. This should mean a lot less work on my part.
But, for now, please remember to serve a side order of sausage with your comments.
Update: This morning I fixed a bug which meant that the sausage was silently deleted if you previewed the comment before submitting, which meant that I had to fish 3 comments out of the junk folder this morning.
I’m also now mandating that you type the word in, as otherwise you’ll get an error message.
