Youtube – Prevent display of “shared on Google+” in YouTube

At this time there is no method in which you can search for your comments that you have made. The following is what was able to be used in the past but no longer works.

1. Go to google.com
2. In google search type the following site:youtube.com "yourusername" inurl:all_comments
3. Click search

This use to pull up all results showing your comments on videos. Once you were able to get to the video you commented on you would be able to edit the comment or remove it.

As far as who sees the comments depending on if you selected "share on google plus". If you selected this it would post the comments to your circles for friends, etc, to see. If you deselected this option there would be no post made to google plus sharing the comment you had made. As the conversation that you posted about on the product reviews said "Product Reviews"... There can be a lag of about 4 minutes before a video comment will post.

I have also never seen a "ghosting" of my comment on my google plus profile or news feed. If I deselect the "share on google plus", it never gets shared and no one will see it. This topic at google is about 2 years old so updates may have been made by now to correct it.

I have done comments, shared and not. The ones I choose to share show in my circles and profile, the other I do not share do not appear anywhere.

If you're using Gmail, you can create a filter so these messages don't hit your inbox. If you don't want any emails from YouTube, you can search for it and then click Create filter. You can add additional criteria on the next page, confirming the results before creating the filter.
