The blue-green color is his dad's comment. There are many other posts of people saying similar stuff as the people marked in black. It's been almost 24 hours, so I don't think they're going to delete the comments on their own.

I was thinking about sending a private message to each of the commenters to gently and kindly encourage them to delete their comments. I was thinking about saying this, "I know your heart is in the right place, but (friend's) family has asked that nobody leave comments on his Facebook page for now. If you could delete your comment and save it for another time, his family would really appreciate it."

However, I've never met his family. He always came over to my house to hang out, so I never actually met them other than maybe once or twice very briefly. I feel like it might not be my place to be sending messages like that. I would do everything I could to avoid any kind of argument or confrontation though. And I have a feeling nobody in his family has the energy to ask those people to delete the comments themselves.

It seems very inappropriate to me that people aren't listening to his dad and deleting the comments, and I really want to do something about it. Would it be appropriate for me to send private, polite messages trying to encourage people to delete their comments?
