Who doesn’t love a kind comment, and yet who likes to support a spammer? Consider this comment, for example:
Just Googled and read the whole article and i must have to say that me and my husband loved reading your post. I liked your site because of the easy language you used to explain things here. Now i can stop my research having found my answer in this awesome article. We bookmarked and will regularly check more quality tips to come from your website. Thanks alot.
How sweet, right? Until you notice her name is “Watch Movies Online!”
Assuming your blogging software already has some good anti-bot intelligence going for it so the spam is few and far between, probably the easiest way to find a spammer out is to google their comment, in quotes. Disheartening, isn’t it?
A few other tell-tale signs:
– Keywords instead of a name
– Links in the comment body
– Name and email address both appear to based on real names that are totally unrelated
And of course you could click on their site to see what they’re selling, but I personally avoid that if I can.
