Is X Zombie Hunter - インプレゾンビ・スパム自動ブロック safe?

Automatically detects and hides spam-like replies in X reply threads.

This extension filters X (formerly Twitter) replies that match patterns such as low-follower verified accounts without Japanese profile text, repeated replies in the same thread, or user-defined blocked keywords. It lets you choose how filtered replies appear, including overlay, translucent display, or full hiding, and supports whitelisting, followed-user exceptions, and disabling filtering on non-Japanese original posts. The store description says analysis runs locally in the browser and does not send browsing data or personal information to external servers.
