The second type are ping and trackback spammers. This is either done by auto-posting articles that others have written without their consent on so called autoblogs. Each post generates at least one pingback to the original site. This can lead to hundreds of pingbacks over time which many webmasters and blog owners publish.

The third and most spammy type are the automated spammers that use specifically designed tools to spam thousands of blogs, forums and every other type of site where content can be posted in hours. Now that we know the different types of spammers we have to discuss how to handle them. This post will mostly deal with automated spammers who post dozens if not hundreds of comments and pingbacks.

Webmasters should use at least one anti-spam tool to block the majority of spam reaching the frontend of the website. WordPress users can for example use Akismet or one of the several other anti-spam plugins that are available. Still, some spam will come through. Today for example a webmaster decided to copy and post more than 300 articles from Ghacks on a website. Each post generated at least one pingback, many multiple pingbacks as the tags and links were kept by that webmaster.

Akismet did not object to these ping and Ghacks ended up with more than 300 accepted and published pings from that blog. Many webmasters would now delete them one by one which takes quite a while. A far better solution is to filter for a common denominator which in this case was the url of the website. All comments, pings and trackbacks that include the domain name of that website were listed giving me the option to mark them all and send them to the spam folder.

There might be situations where this is not possible. Maybe the website or script does not offer the option to bulk moderate comments. There is however another option if the website is making use of a database. This does however require some knowledge about the database as a query has to be run in the administration. Most users will probably use MySql where a basic delete query looks like this:

delete from [table] where [column name] = 'value'

To delete all comments from a specific url in WordPress one would do the following:

delete from wp-comments where comment_author_url ='www.example.com'

It is possible to use other table columns like the commenters IP or email for example. How do you handle mass spam to your website or blog?

Other concerns were that Akismet was not really a free anti spam plugin as webmasters who made more than $500 per month had to order a commercial version for $55 a year. The last concern was probably the most important one as data is send to Akismet servers including the commenter’s IP, user agent or referrer.

One of the main advantages of Antispam Bee is that it does not have to communicate with external servers for the anti spam protection. It is an all in one solution that detects spam not only in comments but also in trackbacks and pings.

The anti spam plugin runs out of the box after activation in the WordPress interface unlike Akismet which requires the WordPress api key. A few options of the free anti spam plugin can be configured in the WordPress settings. Antispam Bee will delete spam messages automatically when they are detected. This can be changed to mark them as spam and keep them for a limited time in the WordPress spam folder. Great for the first time of usage to monitor the performance of the anti spam software.

The main benefits of using Antispam Bee are twofold. It does increase the privacy of the users who comment on the blog as it does not submit data to third party servers which in turn reduces system resource usage which could be noticeable for blogs that receive many spam comments per day (Ghacks receives about a thousand a day).

We have been testing Antispam Bee for the last days and like the performance and spam detection rate a lot. Only one legit comment was flagged as spam by the anti spam plugin. Even better was the fact that comments from users who were usually flagged as spammers (jojo for example) were not moved to the spam folder at all.

Antispam Bee can be downloaded from the website of the developer. The WordPress plugin itself is multi-lingual (at least German and English).

In a form of an online service, reCAPTCHA offers exactly that. After signing up for the service, you’ll be able to place a captcha module on your website and avoid automated abuse while helping to read and store books of the past. With this special type of captcha engine, users are besides writing an already known word correctly into the widget’s field also required to recognize an additional word gathered by digitizing books which the OCR system wasn’t able to recognize due to various defects in characters.

Besides an obvious advantage of this service that makes real use of captcha, there are other great advantages to it. It’s easy to install thanks to plugin support for major CMS like WordPress, it’s accessible for eyesight-disabled people and it is based on high security standards that make it nearly impossible to penetrate. Moreover, the whole system can be quickly updated whenever a vulnerability is found without the webmaster having to worry about it. It’s also capable of IP filtering.

Should you wish for a great, free, customizable service with its own API that transforms waste of time into a useful and valuable activity while protecting your website against the dirt of spam? Here you go.

If you do run a website you might have come upon comments that are posted that contain one sentence saying something unrelated but positive about the website or webmaster. Those comments can be clearly identified as spam because they do not add to the discussion or article in any way.

What is happening here is that spammers are trying to get some bonus points from the spam filter of the website so that his next attempt at posting an entry with an url does not get blacklisted or queued for moderation automatically.

This would be indeed be a great spam preparation method if they would use unique comments on each blog that are related to the article. Since it is not possible to do this and spam thousands of blogs per hour they have to rely on nice remarks about the website which surely pleases some webmasters enough to keep the comment.

It does not really matter if their intention is to get some positive karma or train the spam filter to accept certain words that are used in the comments. The reason behind this is to prepare your website for the spam.

A better variant would be for instance to ask a question which would surely have a much higher rate of being kept. “I did not really understand what you have been writing. Could you please elaborate it a little bit more ?” or sentences like that would probably result in a higher success rate.

I generally delete all content that is either not related to the article that I have written or that does not feel right. Someone who uses ‘Budget Web Host’ as his name is surely to get blacklisted at my site pretty quickly.
