DMCA Requests & Xhamster

This happens repeatedly: I find a video with NO identifying watermark or information, upload it (on its own or as part of a compilation), then I am told there was a complaint and I have 1 strike against this profile. But Xhamster never identifies who made the complaint so I can avoid using one of their videos in the future. This is so fucking obnoxious and I am getting tired of it.
