Considering what is going on, I highly recommend that you delete all of your youtube comments asap. According to Google, it will take a few hours.

You need to hide (or delete) your channel. I hid my channel.

Follow the steps on this website.

The only drawback is that you will not be able to comment on any youtube videos. You can like a video but that is it.
