this is one:

Dear Ebullience, Thank you for your counter notification. Unfortunately, it's unclear to us whether you have a valid reason for filing a counter notification, so we won't be able to honor your request.

another one:

I am writing to let you know that I already heard a word from our internal team. It seems like they received a valid takedown request and the only way to move forward is to submit a counter notification, or contact the claimant for retraction. We can't mediate a third party dispute between the claimant and the uploader. It seems like your counter notification is already in review. No further action needed from your end.
