Signs of playlist theft include mismatched channel names, missing logos, broken EPG data, unstable streams, or playlists that change frequently without explanation. Stolen playlists often contain channels from multiple unrelated sources, inconsistent quality, and duplicated categories. These providers also avoid offering Xtream Codes logins because stolen links are easier to distribute via raw M3U. Glanfy checks for playlist signatures, CDN origin matches, and consistent formatting to verify legitimate providers.
