Bilibili Blocker by Guo Yunhe

Block low-quality or unwanted content by account UID, with subscribed rules and custom blacklists and whitelists

About this extension

Features

Precise UID-based blocking: Identify content by account UID without the false positives caused by keyword matching.
Subscribed community rules: Enable the rule categories you need and refresh the rule lists with one click.
Custom blacklist: Block unwanted accounts directly from their profile pages, including accounts not covered by subscribed rules.
Custom whitelist: Allow accounts matched by subscribed rules; whitelist entries take priority over subscribed rules.
Local management: Blacklists and whitelists are stored only in the browser and do not modify Bilibili's official block list.
Dynamic content support: Automatically process content loaded after the initial page load.

Blocking Rules

FAQ

Why not use Bilibili's built-in block list?

Capacity limits: Bilibili's official block list has a limited capacity, which is not enough to block large categories of unwanted accounts.
Account safety: Adding many accounts to Bilibili's official list in a short period may trigger abuse detection. Bilibili Blocker only filters content locally and does not send block requests to Bilibili.

Why not block by keywords?

False positives: Legitimate educational content may contain words such as “AI” or “finance”.
Performance: Keyword matching requires scanning video titles, while UID matching provides direct account-level filtering.
Maintainability: UID lists are easier to review and maintain than large keyword lists.
