7 Tips To Stop WordPress Comment Spam

This is a guest post by Adrienne Erin.

Open discussions make blogs fun to read and engaging. After all, a one-sided conversation might be satisfying for the blogger who initially writes it, but the fluid nature of subsequent agreement and disagreement is what makes readers click on posts and get absorbed in content. However, not everyone visits a blog with the intention of adding something worthwhile to the conversation. Read on to discover seven ways to give spammers the boot.

Know What To Look For

The first step is to spot spammers when they strike. Often, their comments are peppered with misspelled words, nonsensical phrases and links to their own companies or causes. Also, keep an eye out for comments that have nothing to do with the topic at hand. If you run a blog that focuses on personal finance, yet you're getting flooded with comments about personal injury lawyers, then that's a red flag.

Show That You're Aware

Current posts are one of the clearest indicators of an active blog. However, beyond just keeping your content relevant, interact with your readers, too. Respond to their comments, even just to let them know that you appreciate them taking time to speak their mind. This shows that you're aware of what's happening on your blog, and gives the perception you're not an easy target for spammers.

Put Some Blocks in Place

Spammers commonly reply to older posts. With that in mind, you can opt to close them to comments. This is a reasonable compromise, because while it doesn't shut down the exchange of dialogue altogether, you do encourage timely and appropriate discussions. Also, WordPress has tools that allow you to block posters from using certain words you've frequently noticed in comments made by spammers.

Make Users Register

Sometimes, discouraging spammers is as simple as requiring users to register before they're allowed to make a comment. Bear in mind that this may deter legitimate visitors from taking time to fill out a form. If you're worried about that, consider adding a short note to your blog. Explain that the reason you only permit comments from registered users is because you've become frustrated by the diligent efforts of spammers.

Restrict Link Usage

Limiting the amount of links that can be included in a comment also cuts back on the amount of spam you have to deal with. By going into the Settings panel when you're signed into WordPress, you can adjust things so that users may only include one link per comment. It's also possible to get notifications of users who are posting comments with links at a faster than normal rate.

Ban IP Addresses

If you're dealing with a particularly troublesome spammer, it might be necessary to take decisive action by banning their IP address. WordPress offers plug-ins such as WP-Ban that make it easy for you to see the IP addresses of anyone who is visiting your blog, and ban offenders who've crossed the line. Some of these tools simply show banned users a custom message after they try to make a comment, so you'll never have to interact with them at all.

Make Comments Subject To Approval

If your blog is still at a manageable size, it's smart to insist on approving every comment before it's seen by the public. This isn't a practical solution if you receive hundreds of comments per day, but is an excellent approach if you prefer hands-on methods.

Also, you can tweak a setting which requires a person's initial comment to be approved by a moderator, and gives them freedom to post at will after that. Both of these tactics could require a significant time commitment on your behalf, but they rob a spammer of the gratification of seeing a post appear immediately, too.

Winning the battle against WordPress spammers is not a lost cause. It's best to implement some of the suggestions above gradually, so you can determine which strategies work best. By changing your settings and being more demanding about who's allowed to post and what their comments can contain, you can begin to make headway and let spammers know you're aware of their tricks.
