Sometimes you need to be a user to really feel their pain. This site is a WordPress site. I figured with my security and spam comment plug-ins, I was safe and sound. Then I started getting all of these e-mails about new user registration. Exciting, right? No. These all had reasonable user names but the sign-up email was some randomness followed by hotmail.com or outlook.com. These were robots not people.
I looked at several solutions. There was a popular plug-in called Stop Spammers but the author was going to slow down on maintenance of this one. That didn’t sound good. Another one looked promising but required registering. It sounded thorough but a bit more than I needed. Another one could turn off the notifications but that seemed a little drastic. I did still want to know if a real person registered. There were a bunch of captcha plug-ins but I hate those distorted images. Sometimes I can’t tell what the word is either making the site both robot and human proof. I ended up going with Stop Registration Spam. It could add a question to the registration that should be easy to answer for a human but difficult for a robot. It does add a step to registration but, hopefully, its easier than a captcha. So far, it seems to be working. If not, there are other options.
Finding a WordPress plug-in seems to be a bit of an art. Try searching for different combinations of words and phrases. You can check out stats like its user rating, number of downloads, most recent update, versions of WordPress on which it has been tested, and FAQ. If the plug-in doesn’t work or doesn’t suit your needs, you can deactivate it, delete it, and try another. Good luck finding the perfect plug-in to do the job!
