Cooking up WordPress comment spam, nice and hot!
The internet is not only a place for information, it’s a spammer heaven ever since people realized that they could create computer programs to generate massive amounts of links to help improve PageRank and search engine positions. Lucky for us WordPress users, it’s the easiest platform to spam.
Ever since the spam revolution, search engines have changed their ranking algorithms trying to stop the spammers. The funniest thing about WordPress spammers, is that they are wasting their time. Even if they do succeed in blasting links all over WordPress blogs, it doesn’t help their search engine ranking at all. At one point, this was a successful BlackHat SEO method at one time, but Google no longer follows or indexes comment pages. In an unlikely scenario, the spammers link could get clicked on if the blog owner did not remove the spam comment, so I guess it’s not completely pointless.
Plugins to help stop the spam
The absolute best tool I have found for fighting spam is Akismet. This plugin is present in all new WP installs. With Akismet, you still have to do some spam sifting, but the more times you mark comments as spam and not as spam, the more Akismet learns. The plugin has been around for a long time, meaning that it has gotten pretty good at detecting spam. Most of the time, it does a very good job at detecting spam (by cross-referencing the IP of the author and words in the comment).
When I notice that the same IP or range of IPs are attempting to spam my blog, I pull up the good old handy WP-Ban tool, copy the IP, add a wild card if necessary, and keep them from ever spamming my blog again from that IP or range. This can somewhat be done within the WordPress core, but it is not nearly as powerful as WP-Ban. This plugin allows you to ban IPs, IP ranges, referrer URLs, host names and even user agents. Unlike when banning IPs within the WordPress core, WP-Ban does not let any machine that meets any part of the blacklist’s criteria even access your blog. It also keeps stats of each item such as how many spam attempts were made and whatnot.
When using the WP-Ban plugin, be very careful when banning certain IP addresses, especially your own. If you accidentally ban your IP address, you won’t be getting back into your blog until you acquire a new IP. Blocking certain ranges of IPs can block potential readers. Only ban IP addresses that you know are spamming your blog (ie. Akismet shows multiple spam attempts from the same IP. I have compiled a list of spammer IPs, click here to see them. If you’re unsure if the IP is a spammer, you can check it against the Stop Forum Spam database. This site reveals a lot of information about spammers including IP, email, username, hostname and more.
One of the best ways to keep spam comments from being displayed on your WP blog is to require that all comments be approved by an administrator before they are shown on the post (This can be done in Settings > Discussion > Tick ‘Admin must approve’. You can also set up a blacklist for certain words, ip’s, emails and usernames. This has some disadvantages though… When a spammer hits your site, they normally try to send hundreds of comments, so sorting through all of the comments to find legit ones will be a task.
