It would be very useful if we had the ability to delete files that are flagged for copyright infrigments by using a flag (I'm bad at naming things so can't suggest any names)
Example of what a flagged for copyright file looks like
I think this flag could help detecting these kind of files (as long as you aren't the owner of these files because only the owner can server side copy these while managers of the shared drive can see and download and Content Managers and below can't even see them) capabilities.canCopy
Taken from https://developers.google.com/drive/api/v3/reference/files
It would be relatively easy to ignore all files with canCopy not set. I don't think it is something I'd put into rclone permanently (too specialized) but it would be not too hard to patch it in. Fancy having a go at that?
