Keep personal information on a need-to-know basis
Not every message should be shouted from the rooftops. It’s important to think before you share, since public content can be copied, re-shared and spread around the web by anyone who finds it. Talk to your family about protecting their personal information online, then help them share what they want and protect what they don’t. Some services, like Google+, have stricter sharing settings for teen users than for adults, but many services can be customized to fit the needs of each family member. Talk with your family about what types of information they can share publicly, what might be better to share with just a few close friends, and what should stay private.

Manage YouTube Comments
If someone is making comments that you don't like on your videos or Channel, you can block them on YouTube. This means they won't be able to comment on your stuff or send you private messages.
Choose whose updates you see in your stream
What if someone adds you to their circles, but you're not interested in interacting with them? If you don’t want to block them, you can mute them instead. If you mute a user, you will no longer receive notifications from them or their page.
Control the chatter about your videos
It’s easy to moderate the comments on your YouTube channel. You can choose to delete comments, or to hold comments from certain people or with certain keywords from being published before you review them.
