I figured out how to prevent bots.

I honestly figured out a way to prevent bots even with out the security questions, all you need is one single plugin.

Go to http://www.keycaptcha.com

---

Register for an account

---

Once you sign up, you will be on the dashboard, click add site.

---

Follow all the steps

---

After step 4, you will receive instructions on how to install the plugin, which is just like any other plugin

---

All other things you will have to do will be shown to you after step 4.

So, if you're having problems with bots and can't find a legitimate way to stop them, here is your solution!
