Is anyone getting multiple signups from the same person?
Resolved with a Honeypot
Check to see if the signup plugin you're using has a "Honeypot" feature. The honeypot adds an extra field to the signup form that humans can't see but bots can see. So the bot fills it in. If the field gets filled in then the plugin stops them from completing the signup.
I'm getting multiple signups from Mark Mark firstname.lastname@example.org on 3 of my websites. 1 of the sites is not listed here in my profile page so I don't know where they're coming from. 18 signups from the same name and email address in the last week.
It's not a spam comment, it's a spam signup. I have a signup form on each of my sites where I offer gifts in exchange for email addresses so I can build my lists.
Has anyone else had this problem? I don't know how to stop it. Please help if you can.
Google says I'm not the only one receiving fake signups.
