Liz from YouTube Support announced in a YouTube Help thread that a long requested feature is now available – the ability to block subscribers from your channel.

Why would you want to block specific subscribers? Maybe you got ‘pervs’ watching your videos? Maybe you don’t like certain commentators on your videos? Maybe you are anti-social?

How do you do it?

1. Sign into your YouTube account
2. Go to https://www.youtube.com/profile?user=[YOURUSERNAME]&view=subscribers
3. On this page you’ll be able to see the users who are subscribed to your channel and the thumbnail icon from their channel. Below the thumbnail image you’ll see a “Block” button.
4. If you click the “Block” button you’ll remove the user’s subscription to you, and you’ll also block them if their account is active on YouTube.

After that, Liz explains:

Here is a picture of the block button:

I won’t block you, so feel free to subscribe to the RustyBrick YouTube Channel which is what I use to do my weekly search videos, amongst other videos. I still need to make that page look better, one day – one day.
