Preventing Comment Spam with Google reCAPTCHA

The Internet is a wonderful thing, we can communicate efficiently with people almost instantly. However with convenience also comes irritation in the form of spam and unwanted emails.

One of the most common forms of nuisance emails when running a website is something called Comment Spam.

What is comment spam

Comment Spam is when a bot (automated script) or sometimes a real person posts unsolicited comments or messages on a Blog, forums or your contact form.  You see a lot of this sort of thing on social media in comments on posts that are totally unrelated to the actual comment.

Why do people do comment spam?

There are a few reasons:

  • To send mass junk mail to you and solicit for work etc
  • To capture emails addresses though auto-responders
  • To send malicious links to hijack your computer
  • For old school Black Hat SEO to publish links on websites

You might think it’s a waste of their time, but when they do this to hundreds of thousands or even MILLIONS of websites even if only a few people “bite” that is their return.

What do we to prevent comment spam

You can turn off all contact forms on your website, but that’s not really a commercial option.

The most effective way to block comment spam are to use tools to “sniff” out whether the comment or the user filling in the form is “real”,

To prevent (or at the very least make it much harder) for comment spam to be a problem we are adding the Google ReCAPTCHA to all of the contact and signup forms on your websites. (If you don’t already have this added to your website).

Google reCAPTCHA on a website contact form

What is Google reCAPTCHA?

Google Defines it as:

reCAPTCHA is a free service that protects your site from spam and abuse. It uses advanced risk analysis techniques to tell humans and bots apart.

Will there be any other impact to my website?

Not really the only only change is to any other forms on the website and the members sign-up form will also be protected by this tool to prevent bots from signing up to your site with bogus accounts.

Apart from that there are no detrimental effects on your website.

All of our Flower Store In a Box new website have reCaptcha automatically added and we will be adding this to all of our customers in the next two days.
