CollabDRM are a company that partner with artists, influencers, etc. to claim their copyrighted material on behalf of the rights holders in exchange for a percentage of the earnings. They are a big company that manage copyright claims for a lot of people.
In my eyes that are scammers because they don't seem to properly review counter claims and make copyright claims regardless of fair use of the material. So fuck CollabDRM.
They use both automated and manual claiming tactics across YouTube. You cannot block them from your channel in any way. If you use material of a copyright holder that has partnered with Collab then your videos may get claimed and they will get the ad revenue from those videos.
If you believe their copyright claim is bullshit, then you can dispute it through YouTube. If that dispute is unsuccessful, then email CollabDRM over and over again until they release the claim. If it is legitimate then there's probably nothing you can do.
