Many social media users encounter content from communities they find irrelevant or harmful, but current tools only allow blocking individual accounts or keywords, leaving broader networks unchecked. This gap leads to unwanted exposure, misinformation, and toxic interactions, reducing platform usability for those seeking more control over their feeds.

How Community-Based Filtering Could Work

The idea is to enable users to block or mute entire communities—groups of accounts linked by shared behavior—rather than just single actors. Communities could be identified in a few ways:

• Topic-based: Block all accounts frequently using specific hashtags (e.g., #DivisiveTopic).
• Network-based: Avoid clusters of accounts that retweet or reply to each other.
• Affiliation-based: Filter out accounts consistently engaging with a particular influencer or ideology.

Users might toggle these filters in settings, with options to refine them (e.g., "only block accounts using #XYZ and interacting with @ABC"). Unlike third-party tools, this would leverage Twitter’s native data to dynamically update blocked groups.

Balancing Control and Platform Health

While this could empower users—especially marginalized groups facing harassment—it risks amplifying echo chambers. A phased rollout might start with basic keyword/hashtag blocking (MVP), then introduce network-level filters. To mitigate over-insulation, nudges could encourage exposure to alternate viewpoints after excessive blocking.

For platforms, this could improve retention by reducing toxicity, though defining communities without false positives remains a challenge. Monetization might involve premium customization tools or ad-targeting adjustments to avoid blocked groups.
