Spoiler Shield

🛡️ Spoiler Shield — Hide YouTube Spoilers Before They Ruin It

You queued up the game. You're saving the match for tonight. Then you open YouTube — and right there in the sidebar, a thumbnail screaming "3-1 COMEBACK" with a shocked face. Gone. Ruined.

Spoiler Shield fixes this.

HOW IT WORKS

Spoiler Shield scans YouTube video cards and covers any matching video with a full overlay — thumbnail, title, hover preview, everything hidden. You see a shield instead. When you're ready to watch, click Show to reveal it.

WHAT IT BLOCKS

📺 Channel blocking — Block entire channels by name. Every video from that channel gets hidden, no matter what the title says. Perfect for channels that always spoil results in their thumbnails and titles.

🔢 Score patterns — Automatically detects match scores like "3-1", "4:0", "2–2" in any title. No setup needed.

🔤 Spoiler keywords — Built-in list of common spoiler words (wins, eliminated, champion, finals...) with a single toggle. Add your own custom keywords too — either exact match (whole word) or contains (anywhere in the title).
