Blog spammers, web spammers and spam robot web crawlers (spam bots) are much trickier than regular Email spammers.
Be careful to protect your content from these clever spammers. They disguise themselves as genuine readers and followers. They post flattering and complimentary comments on your articles and posts, hoping you will approve them and allow them to be posted on your site. Once they get on your site, they often steal your content, mislead your true readers to their own site, and even sell your content to their own customers by using link-backs to your site!
When reviewing your reader comments, there are a few simple things you can do to often tell immediately if you have a spammer comment or spam bot comment:
- If you allow comments on your site, set it up so that the commenter must provide an email address in order to make a comment. This is very important and an easy way to often (but not always) see an obvious spammer comment. For example, if their email address is something like email@example.com (fictitious email, I hope) you may have a spammer that is trying to push his own website and products.
- Mouse-over the commenter’s Login Name (not the email). Usually hosting sites and blog providers like WordPress will provide a mouse-over pop-up picture of the commenter’s own site instantly (without you ever having to actually click and enter their site). If you see a pop-up site picture that looks like a site that sells products or services you probably have a spammer. However, be careful! Many of these spammers are very clever and have a facade mouse-over site that may even appear as a real blogger site.
- Read the words of the comment itself. It the commenter speaks specifically about something in your article or web page, that is great and a good chance that it is coming from a legitimate reader and not a spammer. If however, the comment is VERY general and doesn’t mention anything specific about your topic, be cautious as this is the most common give-away of a spammer or spam bot.
- Look at the grammar in the comment. If the grammar is ‘off’ and you see certain words misplaced or used incorrectly, you probably have a spammer or spam bot comment. Often spammers or spam bots will use article spinner tools. These tools will take a general comment and switch around verbs and nouns, which allows them to post the same comment on various posts without being caught by the search engines and the spam catcher applications. This doesn’t happen as often with live human spammers, but even they are beginning to use this tool to expedite their efforts. It’s pretty easy to spot these comments and it is a good indication of a spammer.
- Look at the IP address of the commenter. If you see multiple comments using the same IP address (even if the last three digits are different) there is a good chance you are being spammed.
- You also have the ability set up your blog or website so that ALL comments must be approved by you before they are posted. I personally chose NOT to do this and it has worked fine on my blog site – but only because of the Akismet tool. Any comments that have been automatically posted (so far) have always been by legitimate readers. Further, all spammer comments have been caught (so far) by Akismet and held in my Spammer Box – for my review, my approval, or my deletion. How you set up your own blog or web site is your choice.
- Utilizing a spam catcher tool such as Akismet will help catch spammer and spam bot comments automatically and place them in your Spam folder for your review. Upon reviewing them, you can decide whether to approve them for posting or delete them permanently. Most site providers offer this type of tool free of charge.
