How to Use Your .htaccess File to Block Spammers
Summary:
Spammers constantly find ways to bypass even the most secure systems, often targeting overlooked vulnerabilities. Fortunately, you can use the .htaccess file to keep e-mail harvesters at bay effectively. This method works well because these harvesters identify themselves through user agent files, allowing .htaccess to block them efficiently.Combatting Spam with .htaccess
Bad Bots: These harmful spiders, like e-mail harvesters, can severely impact your site. They can cause excessive bandwidth usage and resource drain, sometimes even leading to server crashes. Because they often ignore the rules in your robots.txt file, the .htaccess file can be used to block them by identifying the bad bots.
A specific code block, when added to your .htaccess file, can block many known bad bots and site rippers. These bots receive a 403 Forbidden Error when trying to access a protected site, reducing bandwidth usage and preserving server resources.
Hotlinking Protection: Bandwidth theft, or hotlinking, occurs when someone links directly to non-HTML objects (like images) on your server. This practice strains your server and costs you money.
The .htaccess file can disallow hotlinking by blocking or rerouting unauthorized users attempting to link to your images or files. Doing so might show a broken image or an alternative image to violators?"like an "angry man" graphic. For this functionality, the mod_rewrite module needs to be enabled on your server.
To disable hotlinking for specific file types, insert a code snippet into your .htaccess file. This file should be placed in the root directory or a particular subdirectory to limit its effect to a specific site section.
Password Protection: .htaccess can reliably password-protect directories. Unlike other methods, .htaccess offers comprehensive security, as there are no backdoor entries. To password-protect a directory, add specific links to your .htaccess file in the desired directory.
This feature requires creating a separate file containing authorized usernames and passwords, best kept outside the web root for security.
Best Practices to Deter Spam
Limit Referrer Publication: Avoid sharing referrer information, as it attracts spammers. Removing this incentive can deter spammers looking to exploit referral data.
If you must publish referrers, support a referral spam blacklist and include the page in your robots.txt file. This tells search engines not to index the referrer page, preventing spammers from achieving high page ranks.
Use rel="nofollow": This attribute denies spammers their desired page rank at the link level, offering robust protection. Ensure all external links in your referrer section carry this attribute.
Reliable Referrer Stats: Gathering referrer statistics via JavaScript and beacon images provides more reliable data than raw web server logs. Consider ignoring raw referrer data for increased accuracy.
Master Blacklist File: This powerful tool can combat spam. Filtering referrers using this blacklist helps identify spam. Though not perfect, it remains a valuable resource.
DNS-based Black Hole Lists: This technique can effectively identify referral spam. By checking IPs against a blacklist, you can prevent listing spammy URLs in your web stats. Avoid querying blacklisted IPs for efficiency once identified.
As blogs grow in popularity, so does spam, due to minimal restrictions on comment posting. Spammers use automated tools to target vulnerable blogs, hindering productive Internet usage. Combatting spam requires vigilance and robust tools like the .htaccess file to maintain a secure and efficient online presence.
