Yes. This video was unlocked only in my channel, because they did not consider my appeal within 30 days and Youtube unlocked my video automatically. But this video is still blocked in my second channel, this video still blocked in channels of my buyers, because my video still registered in ContentID by Sony Music and they continue to act as owners of copyright of my video.
Also, this video was blocked in channel of one Envato Affiliate Competition Winner. I guess he was not the first who got a “strike” on YouTube.
