How To Eliminate WordPress Blog Comment Spam

One of the most difficult problems with any blogging system, including WordPress, is that the comments area is wide open to that scourge of the Internet, spammers. In this case, it’s comment spam.

Comment spam is created by people seeking to boost their Google rankings by having lots of links pointing to their own websites. This causes a wide breed of problems:

• When Google detects meaning spam, they will often block the site it’s imminent from therefore it messes up their ranking system.

• It takes up your valuable time and bandwidth to eliminate these posts.

• If the onslaught about spam is heavy enough, it may result in a denial-of-service attack, intended or not, which is a juncture in which the server tries so hard to post bad information and/or deliver notification emails to you that it denies service to the fair requests. In at least one case, a blogger received over two thousand email notifications of comments that needed approval; as he dealt among these, he continued getting more, ultimately crashing his mail server.

As you can see, even if you have your comments set to post only upon approval, this container be a serious problem. One solution is the Akismet plugin for WordPress.

Akismet Plugin and Other Plugin Options for WordPress

Akismet is designed to help you filter out those malicious spammers, and it’s not hard to get it installed into your WordPress system. Download the plugin, and upload it to the blog directory on your server in the plugins subdirectory under wp-content. Activate from the WordPress plugins menu. If you have a evident that you need the Akismet API, go to the WordPress webstek and look or ask for one.

Here’s the magic: the only instruction in Akismet is “forget that spam was ever a problem.” You don’t have to do anything else at all – the spam fancy simply be bounced. You will not receive a notification, nor devise you become to go out and delete spam.

Another plugin for eliminating spam from bots is the “Did You Pass Math” plugin. This one makes the user enact a endless math problem before submitting a comment. As most humans can handle this and most spambots can’t, it’s pretty likely that a comment posted through this is a legitimate comment. You should add a note concerning cautiousness that your comments will be deleted if you answer the math wrong, though; a wise commenter will usable an offline composition tool, not post directly to the comments area.

If This Still Doesn’t Work

If you still can’t eliminate spammers with these plugins, you can eliminate them by denying them access to your comments area. This does not mean you experience to disable your comments section, only that you need to set up a filter.

It’s not usually quasi simple as just blocking their IPs. Serious spammers practice random IPs, while blocking IPs may get rid of them for a short time, it will finally prevent legitimate comments from being posted. Spammers are also notorious for hijacking spare people’s IP addresses. But as a short-term emergency solution, you can try it. The IP address is included in the information packet for the comment; it’s similar to a traceable phone number. Look for clear patterns in your IP numbers.

Use the .htaccess file to block unwanted IPs from even seeing your blog. For instance, these lines can be added:

order allow,deny
deny from
deny from 456.456.456.*
deny from 789.789.*.*
allow from all

IPs are four-part numbers, such as Typically, if you date a pattern with the first two sections being identical, you can block all IPs about that type by simply listing them as 192.168.*.*, as you see above. This screens forth all these IP numbers. Blocked IPs will get a 403 error page; customize yours so that your juxtapositional specs are listed in case you’re blocking exterior a legitimate user. Don’t use your regular email; a spammer can harvest that too, for a whole new set of problems. Instead, encode your email so that it’s not automatically readable.

When you think you have your problems addressed, you can remove the block from your .htaccess file. If it still doesn’t work, else if you don’t see an IP pattern, it’s likely that spambots are hijacking someone else’s machine to attack your site. In this case, do not use the IP block.

Again, if you don’t have an IP pattern of attack, this may hardly voltooien worth doing. Remember, too, that with IP addresses, the first numbers affect the largest number of computers, like a reverse address: USA, California, Sacramento, X Building, Ste. 101, Joe Schmo. An IP follows roughly the same pattern, with the last like the four sections referring to the specific computer it is attached to.

Google’s Nofollow Attribute

Of course, if it’s a waste of their time to spam you, spammers may just leap you altogether. For this reason, you can use the Google Nofollow quality for links: . This attribute is embedded automatically by modern versions like WordPress.

It does not eliminate links, which is what spammers are working on adding to your site. Instead, it makes those links irrelevant to Google. The end result is that it doesn’t damage your rank in Google, including it doesn’t help a spammer to send data to your site. It also marks you, for spambots looking for an easy target, as a waste concerning time.

This is not an immediate fix. Only it is a nature to suppose your blog resistant to spammers in the future. If you’re already a target, you’ll have to work with it slowly, incorporating all these fixes. If you aren’t a target, the very least you should do is turn on the nofollow option in your WordPress system; this will block any hungry spambots. Upgrade your version, or look for one about the plugins that provides this service for you.
