I'm trying to just display articles and their comments where users deletion field is not 1 and active is NULL, but for some reason my query displays comments from articles where the deletion field is 1. Can someone help me fix this?

Sorry for all the info but I have been stuck on this for about 3 days and really wont to solve this problem ASAP.

MySQL tables

CREATE TABLE users (
    user_id INT UNSIGNED NOT NULL AUTO_INCREMENT,
    username VARCHAR(255) NULL,
    password CHAR(128) NOT NULL,
    active CHAR(32),
    deletion TINYINT(1) UNSIGNED NOT NULL DEFAULT 0,
    PRIMARY KEY (user_id),
    UNIQUE KEY (username)
);

CREATE TABLE articles_comments (
    id INT UNSIGNED NOT NULL AUTO_INCREMENT,
    parent_comment_id INT UNSIGNED NOT NULL,
    user_id INT UNSIGNED NOT NULL,
    article_id INT UNSIGNED NOT NULL,
    comment TEXT NOT NULL,
    date_created DATETIME NOT NULL,
    PRIMARY KEY (id),
    KEY user_id (user_id),
    KEY article_id (article_id)
);

CREATE TABLE users_articles (
    id INT UNSIGNED NOT NULL AUTO_INCREMENT,
    user_id INT UNSIGNED NOT NULL,
    title TEXT NOT NULL,
    summary TEXT DEFAULT NULL,
    content LONGTEXT NOT NULL,
    PRIMARY KEY (id)
);

    INNER JOIN articles_comments ON users_articles.id = articles_comments.article_id
    INNER JOIN users ON articles_comments.user_id = users.user_id
  WHERE users.active IS NULL
    AND users.deletion = 0
