Here are a few options for a WordPress post_tag description, written in Traditional Chinese, with varying levels of detail and focus:

**Option 1: Short and Direct**

* **Description:** 針對各種匿名投訴及意見回饋。 (Addresses various anonymous complaints and feedback.)
* **Rationale:** This is concise and clearly explains the purpose of the tag.

**Option 2: More Detailed and Emphasizing Privacy**

* **Description:** 提供平台，讓您可以匿名提出申訴、表達意見，或檢舉任何不當行為。絕對保障您的隱私。 (Provides a platform for you to anonymously lodge complaints, express opinions, or report any inappropriate conduct. Your privacy is absolutely protected.)
* **Rationale:** This emphasizes the privacy aspect, which is crucial for an anonymous system, and expands on the types of issues covered.

**Option 3: Action-Oriented and Empowering**

* **Description:** 使用此標籤，匿名舉報您遇到的問題、表達擔憂，或提供改進建議。您的聲音值得被聽見！ (Use this tag to anonymously report the problems you’ve encountered, express your concerns, or provide suggestions for improvement. Your voice deserves to be heard!)
* **Rationale:** This description aims to be encouraging and actionable, prompting users to use the tag.

**Option 4: Explaining the Functionality (Targeting Website Users)**

* **Description:** 標示使用匿名申訴系統的文章。您可在匿名的情況下提出回饋、查詢資訊或反映問題。 (Marks articles using the anonymous complaints system. You can provide feedback, seek information or report problems anonymously.)
* **Rationale:** Focuses on clarifying to the website users, when they should expect seeing it.

**Choosing the Best Option:**

The best option depends on the overall tone and functionality of your website. Consider:

* **Target Audience:** Who are you trying to reach?
* **Website Purpose:** What is the website’s primary objective?
* **Level of Informality:** How formal or casual is your site’s style?

I would recommend the **Option 2 or 3** for most use cases, but it depends on the context. Remember to update it in your tag settings within WordPress. You can find this in the “Tags” section under “Posts” in the WordPress dashboard.
