Sorry that I didn't read much. But above comment section there are directly contradicting comments. One person says he may have received 5 DMCA notices and another person says it is not true. I have seen similar very contradictory things in other social medias too. How is this possible? How to quickly find who is lying without spending too much investigating?
I'm not sure anyone is lying here, so much as being misled by the conventional wisdom that YouTube has no incentive to straighten out. "DMCA" is a well-known buzzword, and the shallow understanding is that copyright infringement claims that get content taken down are all under the DMCA umbrella. The deeper understanding is that most of the big content hosts like YouTube have frontline systems that exist outside the DMCA procedure and its associated legal requirements, but YouTube is happy for the DMCA to take the blame for anything that is handled poorly by their own system. Disputes through that system can be escalated to real DMCA takedown notices.
Content-ID is something else entirely - an automated preemptive system. But last I checked, it looked like formal DMCA procedures weren't the only manual complaint alternative.
