Throws SPAM Away

Missing $domain parameter in function call to _e().

The $text parameter must be a single text string literal. Found: $add_ip_addresses

All output should be run through an escaping function (like esc_html_e() or esc_attr_e()), found '_e'.

$_POST['act'] not unslashed before sanitization. Use wp_unslash() or similar

All output should be run through an escaping function (see the Security sections in the WordPress Developer Handbooks), found '" ip_addresses'></div>\n'.

Use of a direct database call is discouraged.

Use placeholders and $wpdb->prepare(); found $comment_spam_select_query

Direct database call without caching detected. Consider using wp_cache_get() / wp_cache_set() or wp_cache_delete().

A function call to __() with texts containing placeholders was found, but was not accompanied by a "translators:" comment on the line above to clarify the meaning of the placeholders.

Detected usage of a possibly undefined superglobal array index: $_POST[&#039;hostbyip&#039;]. Check that the array index exists before using it.

strip_tags() is discouraged. Use the more comprehensive wp_strip_all_tags() instead.

Detected usage of a non-sanitized input variable: $_SERVER[&#039;HTTP_USER_AGENT&#039;]

Unescaped parameter $comment_spam_select_query used in $wpdb->get_results()\n$comment_spam_select_query assigned unsafely at line 666.

PHP file should prevent direct access. Add a check like: if ( ! defined( 'ABSPATH' ) ) exit;

Use placeholders and $wpdb-&gt;prepare(); found interpolated variable $this-&gt;table_name at \t((select count(ip_address) as cnt, ip_address, max(post_date) as ppd, error_type, author, comment from $this-&gt;table_name\n

Processing form data without nonce verification.

In footer ($in_footer) is not set explicitly wp_enqueue_script; It is recommended to load scripts in the footer. Please set this value to `true` to load it in the footer, or explicitly `false` if it should be loaded in the header.

Multiple placeholders in translatable strings should be ordered. Expected "%1\$d, %2\$d, %3\$d", but got "%d, %d, %d" in "（初期設定：一定時間「%d」分以内に一定回数「%d」回スパムとなったら次から「%d」分間）<br>当該IPアドレスからのコメントを強制スパム扱いします。".

File has mixed line endings; this may cause incorrect results

load_plugin_textdomain() has been discouraged since WordPress version 4.6. When your plugin is hosted on WordPress.org, you no longer need to manually include this function call for translations under your plugin slug. WordPress will automatically load the translations for you as needed.

Attempting a database schema change is discouraged.

date() is affected by runtime timezone changes which can cause date/time to be incorrectly displayed. Use gmdate() instead.

error_log() found. Debug code should not normally be used in production.

Resource version not set in call to wp_enqueue_style(). This means new versions of the style may not always be loaded due to browser caching.

Version parameter is not explicitly set or has been set to an equivalent of "false" for wp_enqueue_script; This means that the WordPress core version will be used which is not recommended for plugin or theme development.
