It's like a bad itch; you scratch it and somehow it returns.
Wanting to learn more about comment spam, I did online sleuthing to learn reasons for and actions bloggers can take. (That's what happens when I'm recovering from a cold and staying awake.)
And, I'd failed to re-check comments a couple days after a current post. Sure enough, I found spam that had been left after. This won't be happening again; an Italian proverb states:
When a man deceives me once, it is his fault; when twice, it is mine. Today, this is more popularly translated to: Fool me once, shame on you; fool me twice, shame on me. — Good advice !Everything here may not be practical or applicable for all, but I enjoy sharing info.
What's comment spam?
Sometimes, it's an
Why it's annoying & why moderate it?
Blog authors take time to design a post they hope will entertain or inform or where they can share things of interest. "Real" commenters spend similar time reading such posts.
Comment spam, if left unattended, could make it look like the blog author doesn't care about or read comments left by "real" commenters.
It's even possible that not doing so could put readers at risk. If someone clicks on a fake link in a spam comment, a re-direct might lead to a malware site that could infect a computer with spyware or even a virus.
You can be sure that not only will that person not return, but could alert others to avoid your blog. Wouldn't you?
How to identify spam
Comment links — be careful when you see links to other websites that you either don't recognize or suspect are not legitimate blogger sites. Avoid clicking on them.
Commenter names — many spammers won't use an actual name, but instead use SEO (search engine optimization) keywords like "best design company." If you spot a comment with no name, mark it as spam. The use of keywords in the name field of a comment without a real first and/or last name is almost always the sign of an SEO spammer.
Relevant comment — is the comment related to the blog post? Generic platitudes like nice blog here, great capture, I have bookmarked it, keep posting, your site looks amazing can (but not always) can possibly be spam.
Not all comments like this are spam. "Real" commenters may leave similar ones due to time constraints, yet still want a blog author to know they've visited. Perhaps, you've received some from regular readers. In those cases, you'll need decide about its validity.
Inappropriate language — English is the most common language and a comment that you don't understand could be spam. However, even on English language blogs, those from other countries may comment in their own language. You may well need to use your own judgement in many cases.
There are two major blogging platforms. Wordpress offers plug-ins to combat spam comments through several third-party systems (at added cost). Blogger offers several built-in features. It's the only platform I've used, so here's some of them.
Limiting spam in Blogger
Avoid anonymous comments — Log into your blog dashboard and go to Settings > Posts and Comments. You'll see an Option called Who can comment? Instead of Anyone, choose one of the other options: Registered User, User with Google accounts, or Only members of this blog.
Turn on comment moderation — This step takes time, but many blog authors do it to maintain the integrity of their blog. Go to Settings > Posts, comments and sharing and you'll see the comment moderation option. If you set it to Always and enter email moderation requests to — it prevents any comments from being posted without your approval first.
Receive comment notification email — Go to Settings > Mobile and email where you'll see a field for comment notification email. You can enter up to 10 emails, separated by commas. This option will notify you whenever a comment is left.
Enable CAPTCHA verification — Most spam bots can't surpass CAPTCHA verification. Go to Settings > Posts and comments. You'll see an option for word verification. Enable it, by clicking to Yes and then Save settings. Now to leave a comment, someone will first have to complete a word verification. Be aware that not all commenters may like this additional step especially when reading and commenting on multiple blogs.
Websites implement CAPTCHA codes into registration processes because of spam. Those crazy numbers and letters are a way of checking if the person registering or trying to comment is a "real" human being as opposed to a computer program attempting to spam the site. (CAPTCHA is short for Completely Automated Public Turing test to tell Computers and Humans Apart.)
To check comments
Click Comments > Published
Under the comment, click Delete or Spam to move it to the Spam folder.
To manage comments in Spam, click Comments > Spam
Comments previously marked as Spam will be sent to this folder. You can delete them.
You can check the spam folder not only to see what's been found, but also to make sure that no "real" comments went there in error. If you find one, click Not Spam and it returns to the post comments.
As the blog author/administrator, you can delete or mark a comment as spam, even if it's already posted — nothing is forever — especially spam.
What method(s) do you use to monitor comments — any of these?
