Jenn has been so heavy handed with the deletion of comments. blocking of users and manipulation of what is shown to others, she really has made that her priority in life, far above editing, arguably above Jackson. Perhaps she needs to drop the I'm-an-editor act we all see through and just bill herself as a social media person. I know some people who made decent money doing just this for companies. Her problem is that she wants to wage war with everyone.
As to how to get Jenn to keep your comments? Comment on older videos, or if newer comment under other comments, and the best, post a sob story and finish it with a criticism. Still, she's so over the top these may get taken down too, but they're certainly worth a try.
