Do you have trouble with SPAM signing up to your social networking Site?
There are many ways to help prevent spam from signing up using Google captcha and other methods but one good and easy method adding a checkbox to the sign up as bots can’t tick these, yet.
Go to your Admin Panel > Settings > Profile Questions
Create a new heading I.E. Spam Check
Now create profile a question and name it “Please put a check in the box” (or anything that you prefer). Ensure you have selected its a required Question.
Automated spammers can’t check the box on the sign-up page where the question is so they will not be able to complete the signup.
That’s all and your site should see a significant drop in spam signups
