I'm getting weird spam comments.
A few days ago I removed the email and website field from the comment form. But today I got 180 comments, each with about 20 links. The weird thing is that those comments listed in spam section, with each showing an email address and a website, and they all come from one IP address": 18.104.22.168
How can people type their email addresses and websites when the fields are not there? Is that some kind of spam script that submits those comments without using the comment form at all?
And if so, how can I prevent such scripts from storming my blog with spam comments?
