**Key Considerations when choosing:**

* **Your Blog’s Content:** Choose the description which best reflects the types of articles you will publish under this tag.
* **Keywords:** The description itself can subtly influence SEO. Consider including keywords like “舉報” (report), “違規” (violation), “平台” (platform), “流程” (process), “注意事項” (important notes), and the types of violations you discuss.
* **Reader Understanding:** Make sure the description is clear and easy for your readers to understand.
* **Length:** WordPress allows for a good length for the description, so feel free to add content as long as it is helpful.

**Recommendation:**

I recommend either **Option 2** or **Option 3** — they are comprehensive, clear, and likely to attract the right audience for your “線上檢舉” related content. Adjust the focus depending on the main topics of your posts.
