I expect it happens about 100 times / day - most just don't make it to here. I've had a false copyright claim on a video I posted - it was a recording of a church service where a historic hymn was sung - out of copyright years ago. The algorithm matched it to another recording of the same tune, but different words, and they claimed copyright. I clicked the appeal button, and explained that it was out of copyright. I heard nothing back. As the video was only a test, I only expected about 3 views, and it didn't block the video, just take the revenue, I ignored it.
