Throws SPAM Away

Throws SPAM Away is a plugin developed for WordPress that addresses the issue of comment spam, particularly from overseas sources. The plugin employs several filtering mechanisms to determine whether a comment should be treated as spam and ignored. One of its primary methods is Japanese language detection: if a comment does not contain Japanese text, it is disregarded and the user is quietly returned to the original article without an error message. This detection is performed using regular expressions rather than simply counting double-byte characters, which helps prevent non-Japanese double-byte languages from bypassing the filter. The inclusion of this filter can be toggled on or off in the settings. To prevent attempts to circumvent the language requirement by using the article title, Throws SPAM Away provides a feature that excludes the title's text from its language detection process. The plugin also allows users to specify multiple "NG keywords" (undesirable keywords) separated by commas. Comments containing any of these keywords are similarly ignored, regardless of whether the comment is in Japanese or another language. Users can configure the plugin to require Japanese language presence or rely solely on keyword filtering, depending on their needs. Another filtering criterion is the number of links present in a comment. If a comment contains more than a set number of strings resembling 'http' (with the default threshold being three), the plugin will flag it as spam. For additional protection against automated spam bots, Throws SPAM Away can generate invisible dummy fields controlled by JavaScript. Since legitimate users cannot see or fill these fields, automated programs that do will be identified as spam sources. This feature can also be enabled or disabled in the settings. The plugin offers IP address filtering, allowing users to block comments from specific IP addresses. It can automatically add IPs from previously flagged spam comments to a block list, and users can manually specify additional addresses as needed. Throws SPAM Away is available as a WordPress plugin, and its configuration options are accessible through the plugin's settings.
