Using Captcha
If you own a blog like I do you probably get a lot of spam comments with just people and internet robots trying to get a bunch of backlinks to their site. So what do you do then? You should always use a Captcha modification and add it to the blog. This way when robots try to post their link, they cannot do it in a normal way because robots cannot read what is in images.
Of course you have your good old spammer that’s a person. He or she goes around and posts manually. He or she just copies and pastes a certain message and then manually enters each captcha. That can get annoying and unfortunately, you cannot do much, unless you take away links being posted of course but that won’t get you comments at all. Just try to protect your blog from these horrible bots by putting a captcha modification on your blog, it comes in very handy.
